Survivor.io has run several limited-time collaborations, and two of the most sought-after are the Teenage Mutant Ninja Turtles (TMNT) and SpongeBob crossovers. Because these characters were only available during their event windows, the only way to get them now is to buy an account that already has them. Here is what they are and whether a collab account is worth it for you.
The TMNT collab
The TMNT collaboration brought the four turtles, Leonardo, Michelangelo, Raphael, and Donatello, into Survivor.io as SP survivors. They are prized for genuine combat utility, not just nostalgia. A maxed TMNT character can be a meaningful part of a strong account's power profile, which is why TMNT accounts tend to hold their value well.
The SpongeBob collab
The SpongeBob collaboration is more of a collector's prize. The characters are charming and rare, but their combat relevance is lower than TMNT. If you are chasing a complete roster or simply want the SpongeBob characters in your collection, these accounts deliver, just temper expectations on raw fighting power.
Why collab accounts hold their value
- The characters are no longer obtainable through normal gameplay, supply is effectively fixed.
- Demand keeps trickling in from players who missed the original event windows.
- Many collab accounts are non-transferable, which ties the rare characters to a specific account that can only change hands as a whole.
That combination, fixed supply and steady demand, is what keeps collab accounts from depreciating as fast as ordinary accounts.
Should you buy one?
Buy a TMNT account if you want rare characters that also contribute to combat. Buy a SpongeBob account if completionist collection value matters more to you than raw power. In both cases, check the rest of the stat line, attack, cores, collectibles, so you are paying a fair price for the whole account and not just the collab badge.
