The Cat in the Hat and his many friends.
Thing 1 and 2 and Cat all BFFing. They are best threeway bromances. The Little Cats. Krinklbine and him are frenemies, as are the Cat and the Grinch, though the Cat in the Hat doesn't see it like that. Him, Sally and Nick are at an impass. Foo foo the Snoo and him are like reverse Joker and Batman, and then there's Cat with his kitten and his lost lady love.
