The House Wagon is a multi-tiered mobile home contained with an M Sized Capsule owned by Oolong. It was his emergency capsule and he used it after he, Son Goku and Bulma were attacked by Yamcha and Pu'ar, while they were travelling through the Kung Pao Desert. It contains at least one bedroom, a kitchen, a dining room, a bathroom with a shower and months' worth of food rations. It was rendered un-usable after Yamcha blasted it with his Panzer Faust and it was left abandoned in the Kung Pao Desert.
