Piranha Plushtrap is Plushtrap's Wicked Tides skin released on June 7, 2021. He is Plushtrap's second skin, after Frost Plushtrap.
His environment changes entirely from the original, now being what appears to be a giant lobster pot, and is filled with coral and pirate ship parts.
The Wicked Tides animatronics began the use of a new format for teasing future characters and skins.
While most animatronics are teased either through in-game e-mails or Twitter posts on the FNAF AR Twitter account, all of the Wicked Tides animatronics were teased through scattered puzzle piece pop-ups in-game, which when put together would form a full picture of it.
Dark Water Endo is featured on the item store on its arrival, and presumably for the rest of the event.
Interestingly, Sunken Toy Bonnie and Piranha Plushtrap do not have original workshop animations. Sunken Toy Bonnie reuses Toy Bonnie's workshop animation and Piranha Plushtrap reuses Plushtrap's workshop animation.
