From the Super Mario Wiki
Hoohoo Village is a small village on the base of Hoohoo Mountain during the events of Mario & Luigi: Superstar Saga. The eccentric Hoohooligans live here and there are many caves and passageways linking different places in the village. Sledge and Mallet, the Hammerhead Bros., also make their home here, before relocating to East Beanbean later in the game. Blablanadon lives here and serves as a transport to the top of the mountain. The inhabitants of this village apparently use or used an ancient language called Hooroglyphs as seen on walls of various areas of the village.
