Blitty

The Blocats or Burokyatto are a species that will appear in the upcoming Mario & Luigi RPG 3. They are animate blocks that resemble cats. Brirock, who is their owner, allows them to assist on the adventure. It seems that they will appear on the field during battle, at which point Bowser can use his vacuum command to obtain them as an item.

Once Bowser gets them, he can go to Brirock's shop and leave them there. He gets an extra equipment for that. The reward for finding all Blocats is a new special ability for Bowser.

The new ability involves Blodog. Slide the stylus like you were cleaning Blodog. Then he will rush into the enemies.
