Kuchi Kopi

Kuchi Kopi (くーちい こーぴい) is a fictitious character that has appeared in many forms throughout the animated series of Bob's Burgers. He has been as a book character, nightlight, toothbrush, carrier bag, and a set of walkie-talkies in Bob & Louise's fantasies. Kuchi Kopi is Louise's favorite toy ("collectible" by Louise), and she goes crazy without it. While Kuchi Kopi's origin is still unknown, he is most likely a character from an eponymous Japanese series of books. Bob describes him as "a spirit that can be different things to different people," a likely reference to the ambiguity and unclear definition of the character.

Mom, can you get Kuchi Kopi for me?
What? Your little night light?
Yeah, I left him in the bathroom next to the toilet.
