Fortress of Squalitude is episode 6 of Season 1 of Sonic Boom, the CGI comedy series made by OuiDo! Productions with Sega of America. It premiered in the United States on 22 November 2014 on Cartoon Network.
Synopsis

Nobody at Sonic’s shack appreciates the effort Amy puts into lunch, so when Eggman turns up needing a designer, she is all ears. Modern Lair Magazine nearly passed on his fortress for being old-fashioned, and he has a week to fix it.
Given a free hand, Amy goes all in on her own taste, angel costumes for Orbot and Cubot included, and the magazine’s scout, Gunther, loves the result. Eggman takes the credit, and when Amy tries to quit, he locks her in a cage as his permanent decorator.
Her friends, who have learned that meals without Amy are grim, are told at the door that she wants nothing more to do with them. Sonic doesn’t buy it. Via the sewers and a hammer-sized hole in the wall, the team springs her, and she quits in person while they wreck the place, just as Gunther arrives with the photographer, Diane Aardvark, who fires him on the spot. As a consolation, Sonic offers her his shack to make over instead, as long as she leaves his coconut husks alone.
