Wazzat

Wazzat / Wasurenbo (わすれん帽 Wasurenbou) is a Fushigi Class, Wind-attribute Yo-Kai ranked E that was once a hat.

Appearance
Wazzat is a green yokai that resembles a top hat. It has thick and gummy purple lips that form the brim with scattered teeth. It has a red bow or ribbon around it. On top are two eye-stalks or antennae with a swirly disk at the tip.

Personality
In the anime, Wazzat starts out appearing haughty and shows off his power to Keita. He also thinks very little about cheating. However, it is revealed that he actually felt both lonely and abandoned since he was forgotten by his previous owner.

Powers and Abilities
Wazzat has the power to "eat" anyone's memory, causing them to become forgetful. He does this by biting or sitting on top of their head. When he does, a very light blue mist comes from his eyestalks. He can remove memories selectively and can sometimes do it by accident, such as when he removed Keita's memories when he offered to shade his head for him.

History
Wazzat was once a normal hat before his previous owner stopped wearing him. Then he became a yo-kai.

Name Origin

 * "Wazzat" is a corruption of the English phrase "What's that?" and the word hat. It could also be a play on words that this Yo-kai was an ordinary hat before he became a spirit ("was a hat.") His name may also be an allusion to the term whatchamacallit, a person, place or thing that is unremembered or unidentifiable ("What is that"?)
