Mikey Gets Shellacne

Mikey Gets Shellacne is the fifth episode of the second season of Teenage Mutant Ninja Turtles (2012 TV series) and the thirty-first episode of the series overall. It aired on November 16, 2013.

Plot
Michelangelo plays with some retro-mutagen, which contracts a dangerous infection that mutates out of control.

Synopsis
Michelangelo plays with some rejected retro-mutagen samples and contracts a dangerous infection that mutates out of control. They head to the remains of TCRI to find a molecular centrifuge to make an antidote for Michelangelo. Meanwhile, Karai sends Dogpound to find Baxter Stockman so that he can maintain the Foot Bots. When both the Turtles and Dogpound find Baxter Stockman in the remains of TCRI, they fight to claim him. When Michelangelo traces Baxter Stockman to his old lab, an incident with the mutagen at Baxter Stockman's lab causes Dogpound to undergo a second mutation, turning him into a stronger form that Mikey calls "Rahzar".

Trivia

 * The sound effects from Michelangelo's first "acne fantasy" (where the giant figure is attempting to pop him) come from Nintendo's Donkey Kong game.
 * Like Shredder before him (in a nightmare Splinter had), Rahzar pays homage to A Nightmare on Elm Street's Freddy Krueger, by scraping the wall with his claws.
 * This is the first episode where Karai interacts with Fishface, Dogpound, and Baxter Stockman
