Pumpkin Head (Su)
3/day, a boundfat can drop a pumpkin from the sky upon its foe within 15 feet from himself. The falling pumpkin must succeed at a range touch attack (+9) and deals extra damage based on the number of hit points the boundfat has lost from max. Pumpkin head deals 1 point of non-elemental damage to a target. This damage is increase by 1d4 for every 5 hit points missing to a maximum of 10d4. Blue mages may learn this ability as a 1st level spell (Knowledge: Planes DC 17).

As a move action, a boundfat can roll itself up into a spiny ball. While rolled up, it gains a +3 enhancement bonus to its existing natural armor, and any creature attempting to grapple the boundfat takes 1d6 damage on making a grapple check. While rolled up, a boundfat cannot take an action other than leaving this state or casting a spell. The boundfat can leave this state as a move action.
