Ninja Rabbid is a Rabbid in mock Ninja Turtle gear, as a result of Ubisoft having the license for TMNT games starting in 2007.
The first appearance of a Ninja Turtle-esque Rabbid was in Rayman Raving Rabbids 2, where TMNT-like gear was available as an unlockable costume.
Ninja Rabbid appeared as a character unto itself in Teenage Mutant Ninja Turtles Smash-Up. It wears a purple bandana, a toilet seat as a carapace, and fights with spatulas.
