Hoohoo Block

Hoohoo Blocks are round purple blocks in Mario & Luigi: Superstar Saga. They can be found at the top of Hoohoo Mountain and are used to make Hammers.

When Fawful blocked the way to Mario and Luigi by putting a rock in the way, they decided a hammer would break the rock. Mario and Luigi met the Hammerhead Bros., who could make hammers but needed Hoohoo Blocks. Mario and Luigi went to the top of Hoohoo Mountain to get Hoohoo Blocks so they could get their hammers.
