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.
Houzzat can also be found at Gogo Junction inside Mystery Way.
He can also be freed from the Crank-a-kai with Yellow coins in the present.

(When you talk to Houzzat again): "So you found Houzzat. Now you want something, don’t you?" "...Huh. You already have it?"
