YMO-104 is a giant space potato monster. YMO-104 was in episode 28, season 4 in the anime.


It was a gift from Giroro's father on Giroro's request. Giroro had not known it was a monster until it became one. Giroro and Garuru fought it together but was unsuccessful. Natsumi came in her battle suit and sliced the monster in two. YMO-104 only says "Oh, potato!"
