Sneaky Lying Cheating Giant Ninja Koopas - S1-E2
Continuity mistake: When the Piranha Plant bites Mario, Mario's raccoon tail changes from brown and black to red and cream, while his brown raccoon ears turn red like his cap. In the same shot, the Piranha Plant's tongue changes from yellow to pink. In the same shot, when Raccoon Mario turns back into his normal form, he still has raccoon ears for a short time. (00:05:02)
