Blitty

The Blocats or Burokyatto are a species that appear in Mario & Luigi RPG 3. They are animate blocks that resemble cats. Brirock, who is their owner, lost them sometime before meeting Bowser. They're trapped within enemies during battle, so Bowser must 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 extra equipment for that. The reward for finding all fifteen Blocats is a new special ability for Bowser. The new ability involves Blodog. Players must slide the stylus like as if they were cleaning Blodog. Then he will rush into the enemies. If the player receives an "excellent" rating on their attack, the Blocats will join in as well.
