This page is for Bear-O (song), the song. For the object, see Bear-O.
"Bear-O" is a song Mabel sings while performing an act that made everyone hate her childhood puppet Bear-O.
Mabel performs the song for a group of children in a flashback during the events of "Tooth." After one of the arms of Bear-O falls apart, the audience is visibly unsettled by the puppet, crying and screaming at its creepy nature.
They're quite a pair, Mabel and Bear-O, Her un-bear-lievable bear!
