Kingdom Hearts 358/2 Days
These mid-sized Heartless begin a countdown to self-detonation if you deflect their head-butts with a block. Strike them during the countdown to send their payload hurtling into other enemies.

TIP: Ice-based attacks like their explosion can freeze you, robbing you of the ability to move.
