Why Does Louise Wear Bunny Ears in ‘Bob’s Burgers’?

Spoiler alert! This article contains spoilers for The Bob’s Burgers Movie.

Throughout the entirety of Bob’s Burgers, Louise Belcher wears her iconic pink bunny eared hat. Louise has never removed the hat onscreen, and even in episodes where it’s been lost or stolen, she has always found a substitute. Neither the show nor its creator, Loren Bouchard, has offered a solid explanation to why she wears the ears until now.
