Mansion Bōma

Yashiki Bōma (ヤシキボーマ): A house-like Bōma Beast who can turn any human residence into a deathtrap, sealed away on Hibarizaka Hill where a house was built, his power labeling it a haunted house. Sensing the Bōma Beast, Jarmin removes the sealing nail to release Yashiki Bōma and enlarges him into his flying phantom house form for her envy-driven scheme to flood every house in the country. Managing to use the sealing nail to weaken Yashiki Bōma back to his normal form, Turbo Robo destroys the monster.
