"The Pulverizer Returns!"

Air Date
May 11th, 2013

Synopsis
Splinter has the Turtles switch weapons as part of their ninja training which doesn't go well during a fight with the Foot resulting in Splinter confiscating their weapons and having them use whatever is nearby as makeshift weapons in combat. Meanwhile, Shredder learns about the mutagen from the captive Kraang operative where he states that the mutagen has unpredictable results. When Shredder plans to create an army of mutants, the Turtles must rely on the help of the Pulverizer (who was recruited into the Foot) who volunteers to gather information on the inside on their behalf. When he carelessly agrees to be a subject for a stolen supply of Kraang Mutagen, the Turtles' rescue mission (where they managed to follow Splinter's makeshift weapon advice) goes horribly wrong when Pulverizer mutates into a mutant blob with visible organs. After the mission, Donatello vows to find a way to restore Pulverizer to normal. The captive Kraang operative states to Shredder that they now share a common enemy in the Turtles.
