Harold is a minor imaginary friend who appears occasionally throughout the show.
Appearance[]
Harold is a small, blue balloon-like imaginary friend with blue arms and legs and big, white eyes. The mouth of the balloon appropriately serves as his own mouth. Whenever he lets air out of his body, he deflates like a typical balloon.
History[]
Harold first appears at the very beginning of "Store Wars". When all of the imaginary friends are decorating the house for Madame Foster's birthday party, Harold inflates a balloon, and in the process deflates himself. Afterwards, Harold has made a few non-speaking background appearances, in both his inflated and deflated forms.
