Defense: Feeds the hunger guy a bomb clearly disguised as an apple and explodes.
Attack: Plays "Those Endearing Young Charms" on a xylophone, which make you explode.
Defense: The fish turn out to be boomerang fish and fly away from me before they get close.
Attack: Those same fish come back to attack you.
