Hypno-Potamus and Warren Stone's apartment

' and ' share an apartment together in Rise of the Teenage Mutant Ninja Turtles, first appearing in the episode Warren and Hypno, Sitting in a Tree. Though the original arrangement was as friends and roommates and they refer to each other as such, they have actually nested into a romantic cohabitation together with the apartment becoming their home.

Soon after the apartment is shown, it is severely damaged by Baron Draxum, who arrives seeking to claim the Kuroi Yoroi gauntlet in Warren's possession. Draxum knocks down the pair's front door, then destroys an entire outer wall of the apartment in pursuit of them as they make their escape with the gauntlet.
