Houzzat is a light purple-pink colored box like Yo-kai having arms and orange lips with jagged and separated teeth. As his name would imply, Houzzat has a miniature yellow room with furniture inside his mouth.
Houzzat often experiences bouts of amnesia from time to time. This leaves him in a constant state of confusion, always wondering who he is, where he is, etc. Sometimes, this gets to the point where even if he's mid-conversation, he'll suddenly forget everything and start all over again. He speaks in a primitive, somewhat childish way, referring to himself in the 3rd person and uses "me" instead of "I".
Houzzat can eat a person's memories with greater efficiency and capacity than Wazzat, to the point of causing amnesia.
