The backwards house

You end up breaking into an abandoned house at night with your friends, but they abandon you and sneak out. You hear an old tube TV creaking, playing an old cartoon with some animal-like characters, such as a half-shark girl with a long tail and fins, characterized as Shy Shark, among others like Curious Cat, and a pet weasel that always scratches most people who enter. Suddenly, you fall asleep in the living room where the old cartoon was playing. Confused, you walk around and see the characters.
