tokidoki Mermicorno Guide: How the Mermaid Unicornos Work, the Series, and Magical Tides

Somebody in your house has seen a little vinyl unicorn with a fish tail, and now they want one. Maybe it was a collector's shelf photo, maybe a kid found the name through a cartoon, maybe you opened a tokidoki blind box expecting a Unicorno and pulled something with fins. Either way, the question is the same: what is a tokidoki Mermicorno, and how is it different from the Unicornos everybody already knows?

This guide is the family-friendly answer: the story, the visual tells, how the numbered series and themed sets relate, every figure in the current Magical Tides set, what the Electra special edition is, and how to buy sealed boxes in Australia. Where a detail comes from collectors rather than from tokidoki itself, we say so.

Quick Answer

A Mermicorno is a tokidoki Unicorno that, in the brand's story, rode a shooting star into the magical sea and came out half Unicorno, half fish. The horn stays, the legs and hooves are replaced by a fish tail, and the figures come in the same random blind box format as Unicornos, usually nine designs per set with one chaser. Sirena was the first Mermicorno, debuting alongside Unicorno Series 4 at San Diego Comic-Con in 2015, and the line has since run to at least seven numbered series plus themed sets. The current themed set is Magical Tides, sold in Australia as a Magical Tides Mermicorno blind box, with a separate open-box Electra special edition.

What Is a Mermicorno?

tokidoki tells its character stories in a couple of sentences each, and the Mermicorno story is short. Unicornos are ponies that wandered through a magic waterfall and became unicorns. Some of those Unicornos then rode a shooting star into the magical sea, and the sea changed them into something half Unicorno and half fish. That is the Mermicorno: the ocean branch of the same family, not a separate species.

The first Mermicorno was Sirena. She debuted alongside Unicorno Series 4 at San Diego Comic-Con in 2015, and the Mermicorno spin-off line dates from that 2015 to 2016 window. Sirena is still the face of the line, and she keeps turning up in later sets, including as a chaser.

If you are new to the whole idea of a tokidoki blind box, the Unicorno blind box guide for Australia explains the silver foil bag, the case pack of eight, and the printed chaser ratio. All of it applies to Mermicorno boxes too.

Mermicorno vs Unicorno: The Tells

Put a Mermicorno and a Unicorno side by side and the difference is obvious from across the room. A Unicorno stands on four legs with hoof sections on each one, small wings at the neck, and a single horn. A Mermicorno keeps the horn and the same face, but from the middle down it is a fish: a curved tail with fins where the legs would be, so the figure sits or reclines rather than standing. Most of the ocean detailing lives on that tail.

The face is the same because the artist is the same. Simone Legno, tokidoki's founder, draws every female character with a single eyelash and every male character with none. That one eyelash is the tell collectors use across the whole brand, and a quick way to spot a knock-off that got the shape right and the face wrong.

In the hand, the two lines share the same materials and scale. Current Unicorno and Mermicorno blind box figures are both listed at approximately 70 mm on tokidoki's product pages, ship in the same style of box with the same foil bag, and pack in the same case of eight.

How Mermicorno Fits Next to Unicorno, After Dark, and Wonder Voyage

Think of tokidoki's figure lines as one family tree. Unicorno is the trunk, with numbered series since 2011 and themed sets on top. Mermicorno is the ocean branch, with the same blind box format, the same chaser system, and the same 1 in 48 ratio tokidoki prints on its standard product pages.

Where it gets confusing is the crossovers, and a lot of collector chatter gets this wrong. After Dark Skeleton is a Unicorno set, not a Mermicorno set. Its nine designs are skeleton versions of Unicorno favourites like Stellina, Dolce, and Fumo, and its chaser is Sirena, the original Mermicorno, in skeleton form. So a Mermicorno does appear in an After Dark box, but as the 1 in 48 chaser of a Unicorno line. For the full picture of the After Dark family, including Masquerade and the numbered After Dark series, read the tokidoki After Dark series guide. The set itself is listed as the After Dark Skeleton Unicorno blind box.

The other crossover is on cardboard. KAYOU's tokidoki Wonder Voyage collectible cards put the character families on cards, and collectors opening Series 2 packs report Mermicornos among them. Those are collectible cards, not figures, with their own rarity system, covered in the KAYOU tokidoki Wonder Voyage cards guide.

The Numbered Series and the Themed Sets

Mermicorno has two kinds of release, the same as Unicorno. The first is the numbered series: Mermicorno Series 1, Series 2, and so on, each a fresh set of ocean-themed designs. Collector databases list the numbered Mermicorno line as running to at least seven series, and "Mermicorno Series 7" is a live search term. We do not print a dated list of every numbered series here because we have not confirmed each one against tokidoki's own pages, and we would rather leave a gap than invent one.

The second kind is the themed set, sold under a name rather than a number. Magical Tides is the current one, and it is the set you are most likely to find sealed in Australia. Themed sets follow the same rules as numbered series: nine designs, one chaser, a case of eight, and the same printed ratio.

Magical Tides, Figure by Figure

Magical Tides is a nine-design Mermicorno blind box set at approximately 70 mm, packed in cases of eight, with a chaser ratio of 1 in 48 printed on tokidoki's product page. The set's signature is its finish: semi-transparent details and iridescent surfaces that catch the light like water, which is why it photographs so well on a shelf. Each box also holds a paper insert with the character list and a sticker.

The names do most of the describing: Kelpy, Jellyfina, Abalona, Pearletta, and Delphine each borrow from something in the sea, and Shellscape and Mishell lean on the shell theme. tokidoki's product page does not publish a per-figure description, so the confirmed set-wide features are the semi-transparent parts and the iridescent finish.

Ophelia is the chaser, and the ratio behaves the way the printed number says it should. One collector on r/Tokidoki ordered a full Magical Tides case direct from tokidoki, opened all eight, and got no chaser, closing with "the hunt continues for Ophelia". That is not a faulty case. At 1 in 48, a case of eight holds a chaser roughly one time in six, and that collector was in the other five. Another collector offered their Botanical Harmony chaser in trade for the new Mermicorno chaser, which is how Ophelia usually changes hands: chaser for chaser, between collectors.

Electra Special Edition vs the Ophelia Chaser

Magical Tides has two figures that both sound rare, and they are rare in completely different ways.

Ophelia is the chaser. She is inside the blind box run at 1 in 48, sealed in the same foil bag as every other figure, and there is no way to buy her by name from a retailer. You get Ophelia by opening boxes or by trading with someone who did.

Electra is a special edition. She is sold openly, in a labelled box, under her own name, with no random element at all. Her finish is the same semi-transparent detail as the rest of Magical Tides plus a holographic ultra gloss, and she comes with a sticker. "Special edition" in tokidoki's vocabulary means exactly this: a single named figure that sits alongside a blind box set, bought on purpose rather than pulled. In Australia she is listed as the Magical Tides Mermicorno Electra special edition.

For a family buying their first Mermicorno, the choice is simple. If the point is the surprise, buy blind boxes and treat Ophelia as a bonus. If the point is one specific figure with no risk of a duplicate, buy Electra.

The Aquarium Shelf

Mermicorno collectors have a display habit Unicorno collectors mostly do not: the aquarium. Because the figures have translucent tails and iridescent finishes, people arrange them like a fish tank, at different heights on risers, sometimes behind glass, sometimes with blue backing so the semi-transparent parts glow. A "Rate my aquarium" post on r/Tokidoki drew a thread of collectors asking where the display case came from. At desk scale, another collector posted Electra inside a thrifted glass candle holder, which suits a translucent figure.

Mermicornos also inspire customs. The two highest-scoring r/Tokidoki posts of August 2026 were both Mermicorno customs: a jellyfish Mermicorno that reached 446 points, and water lily Mermicornos that other collectors said looked like they had come from tokidoki itself. That is a fair measure of how much affection the ocean branch gets.

Mermicorno Starfall: Why Kids Search the Name

If a child asked for a Mermicorno by name, the name probably came from a screen rather than a toy shelf. Mermicorno Starfall is an animated show that shares the Mermicorno name, and Australian Google Autocomplete for "mermicorno" now leads with it: "mermicorno starfall characters", "mermicorno starfall episodes", and character names from the cartoon. This is a guide to the figures, so we will not describe the show, but the show and the blind box line are two separate things. A kid who loves the show will recognise the figures; a collector who loves the figures may never have watched an episode.

Buying Mermicornos in Australia

Most Mermicorno chatter online comes from American collectors, and the shops they name are the US chains and tokidoki's own online store. When an Australian collector finds Mermicornos locally, it tends to be a one-off seller clearing loose figures in a Facebook group rather than sealed boxes.

Our tokidoki figures range lists the sets we carry, dispatched from the Central Coast, NSW, via Australia Post. For Mermicorno specifically, the two listings are the Magical Tides Mermicorno blind box and the Magical Tides Mermicorno Electra special edition. Prices live on the product pages. Every blind box is random, and no purchase, including a case of eight, comes with Ophelia attached.

Frequently Asked Questions

What is a tokidoki Mermicorno?

A Mermicorno is a tokidoki Unicorno that, in the brand's story, rode a shooting star into the magical sea and became half Unicorno, half fish. The figures keep the horn and face but have a fish tail in place of legs, and are sold in the same random blind box format as Unicornos.

How do I tell a Mermicorno from a Unicorno?

Look at the lower half. A Unicorno stands on four legs with hooves; a Mermicorno has a curved fish tail and sits or reclines. The face, horn, and single-eyelash style are the same on both, because Simone Legno draws every tokidoki character the same way.

Which Mermicorno is the chaser in Magical Tides?

Ophelia is the Magical Tides chaser, at the 1 in 48 ratio printed on tokidoki's product page. She is sealed in the blind box run like every other figure and cannot be bought by name. Collectors who want her without opening boxes usually trade chaser for chaser.

What is the difference between Electra and a chaser?

Electra is a special edition, sold openly in a labelled box under her own name with no random element. A chaser is the rarest figure inside a blind box run, found only by opening boxes. Electra adds a holographic ultra gloss to the Magical Tides finish and is the pick if you want a specific figure rather than a surprise.

Is After Dark Skeleton a Mermicorno set?

No. After Dark Skeleton is a Unicorno set of nine skeleton-styled figures. Its chaser is Sirena, the original Mermicorno, in skeleton form, which is why the two lines get mixed up.

Do I get the chaser if I buy a full case of Magical Tides?

No. A case is eight boxes and the printed ratio is 1 in 48, so on average about one case in six holds an Ophelia. A collector on r/Tokidoki who ordered a full case direct from tokidoki opened all eight and got no chaser, which is the ratio working as printed.

Are Mermicornos on the KAYOU tokidoki Wonder Voyage cards?

Yes, according to collectors opening Series 2 packs, who report Mermicornos among the character families. Those are collectible cards rather than figures, with their own rarity tiers.

Where to Start

If this is the first Mermicorno in the house, start with a couple of boxes of the Magical Tides Mermicorno blind box for the surprise, and add Electra if someone wants a sure thing for the shelf. Everything else we carry, including the Unicorno sets and the Wonder Voyage cards, is on the tokidoki hub.
