Collecting art toys as an adult means hunting down pieces with real character. While standard SpongeBob merchandise focuses endlessly on SpongeBob and Patrick, the Pop Mart SpongeBob Fish series 2 collection highlights the background citizens of Bikini Bottom. Known officially as the Residents of Bikini Bottom – Whimsical Plush Part 2, this lineup converts iconic meme-tier background fish into soft plush keychain pendants.
What I like about Series 2 is that it leans even harder into the weird background characters that make SpongeBob so memorable. Not every design hits equally for me, but a few of these are genuinely more fun than another SpongeBob or Patrick release. Here is the full lineup, the pulls I like most, and whether I think a single box or full set makes more sense.
Complete lineup and breakdown of Pop Mart SpongeBob Fish Series 2
The Pop Mart SpongeBob Fish series continues to shine because it turns minor show characters into centrepieces. Each blind box contains a plush fish standing roughly 14 cm (5.5 inches) tall, equipped with a zinc alloy clasp to hang on backpacks or keys.
Standard figures in Pop Mart SpongeBob Fish v2
The regular set of the Pop Mart SpongeBob Fish v2 features six distinct characters based on classic episodes:
- Mail Fish: My favorite of the regular six. The tiny satchel and miniature fabric mail give it more personality than most plush pendants in the set.
- Scientist Fish: One of the simpler designs, but the glasses and lab outfit make the character instantly readable. Cute, although not the first one I would chase.
- Bully Fish: The exaggerated shoulders work surprisingly well in plush form. It is one of the funniest pulls, especially if you recognize the character immediately.
- Explorer Fish: A solid design, but probably the least memorable of the six for me. The adventure outfit is nice, although it gets overshadowed by the more ridiculous characters.
- Crutch Fish: Exactly the kind of oddly specific background character I want from a SpongeBob collection. The cast and crutches make this one much more interesting than a standard character plush.
- Mascot Fish: Easily one of the strongest bag charms in the set. The Glove World outfit gives it a completely different silhouette from the other five.
If you liked the first Bikini Bottom Buddies plush series, I think Series 2 has the more interesting lineup overall. Mail Fish, Crutch Fish and Mascot Fish all have accessories or outfits that give them more visual personality, although Series 1 still has some great individual characters of its own.
The hunt for the Pop Mart SpongeBob Fish secret
The chase figure is the Pop Mart SpongeBob Clown secret, with a stated 1:72 pull rate. It is easily one of the most distinctive designs in the collection, and naturally it carries a much higher aftermarket price than a regular blind box. Resale prices can move quickly, though, so I would check current listings rather than treat any one price as its fixed value.
Pricing and value comparison across SpongeBob Pop Mart releases
| Collection Name | Format / Type | Retail Price (USD) | Primary Appeal |
| Residents of Bikini Bottom Part 2 | Plush Keychain Pendant | $19.99 | Meme-tier background fish, daily bag accessory |
| Bikini Bottom Buddies Part 1 | Plush Keychain Pendant | $17.99 | Working Fish, retro show nostalgia |
| POP MART SpongeBob Krabby Patty | Vinyl Figure | $19.99 | Food-themed display figures for shelves |
At $19.99 per blind box, Series 2 sits in roughly the same price range as several other current SpongeBob POP MART releases. The bigger question is what you actually want from the collection. The fish plush pendants make more sense if you want something you can clip onto a bag or display with a softer, more playful look, while a series such as POP MART SpongeBob Krabby Patty is better suited to collectors who prefer traditional shelf figures. Personally, I find the background-fish concept more interesting, but that comes down to the type of collectible you enjoy.
Should you buy singles or a full set?
If you only want Mail Fish, Mascot Fish or another specific design, buying random singles can get expensive quickly because you may pull characters you do not want. In that case, a confirmed opened figure from a reputable seller can make more sense than repeatedly gambling on blind boxes.
A sealed six-box set is the better option if you genuinely like the whole lineup. You receive six different designs rather than duplicate regular figures. If the secret Clown appears, it replaces one of the regular characters in the set rather than being added as a seventh figure.
You can buy through the official Pop Mart store or at physical POP MART locations. If you prefer shopping in person, we also have a guide to some of the largest Pop Mart stores in the US.
Frequently asked questions
- What is the secret figure in Pop Mart SpongeBob Fish Series 2? The secret is Clown, with a stated pull rate of 1:72.
- Does a full box of SpongeBob Fish Series 2 contain duplicates? A sealed six-box set contains six different designs rather than duplicate regular figures.
- What happens if you pull the secret in a full set? The secret replaces one of the six regular figures, so pulling it does not give you seven characters.
- Is Series 2 different from the first Bikini Bottom Buddies plush series? Yes. Series 2 uses a different group of Bikini Bottom background characters, including Mail Fish, Scientist Fish, Bully Fish, Explorer Fish, Crutch Fish and Mascot Fish.
Final verdict on the Bikini Bottom fish collection
Series 2 works best for SpongeBob fans who get more excited about weird Bikini Bottom side characters than another version of SpongeBob or Patrick. Mail Fish and Mascot Fish are my strongest regular pulls, while Explorer Fish is the one I would be least disappointed to miss.
I would not automatically buy a full case, though. If you only love one or two designs, buying a confirmed figure may be the smarter move. But if the whole background-fish concept is exactly your kind of SpongeBob humor, this is one of the more fun POP MART collaborations to collect as a set.
