What is the shortest possible mate in Tinyhouse?

the ferz is the spiky one, and the wazir is the round-head guy

Sorry for reopening this topic, but just saw this game, and wondered whether it's the fastest possible stalemate : https://www.chess.com/variants/tinyhouse/game/91483812/8/1

Thanks in advance !
