Klunk (In the original 2003 style)
While enjoying Christmas Eve on the surface, Michelangelo finds a stray male cat that approached him while he was making a snow angel, and names him Klunk and decided to keep him as a pet. Klunk was caught up in a Purple Dragon battle but escaped unharmed with Mikey. Mikey then takes Klunk to live in the lair with him and his family.The Christmas Aliens
When the Foot Mystics used their ninja abilities to plague the minds of the Turtles's and Splinter's, they dreamed Klunk drowned when Bishop flooded their lair and Mikey tried to rescue him, but failed. Once the dream was over, Mikey was relieved to see Klunk was okay.Bad Day
When the Foot Clan eventually attacked the lair, Michelangelo, along with Klunk, escaped on the Turtle Tunneler and then, after a brief chase, he faked their deaths by jumping out of it just as it was going to be destroyed. Hiding in a metro tunnel to rest, the two were eventually found by Leonardo: at first Klunk didn't recognize him and hissed, but then, when Leo called for him, the kitten understood and allowed him to pet him. Taken to the future new lair, Mikey asked Leo to find them food; both for the Turtles, for Splinter and especially Klunk.
