Capsules appear as clear cylinders with green caps on both sides of them.
Capsules can be opened by hitting them with one of the heads of the angry heads. Two types of capsules exist: star capsules and heart capsules.
|Ability||Granting the player points|
Star capsules are the first type of capsule introduced in Knuckleheads.
Star capsules appear as usual capsules, but only with a spinning silver star in it.
Star capsules appear quite often throughout Knuckleheads, appearing in hard to reach areas and along the pathway to the end of the level. Smashing them gives the player ten points.
|Ability||Restores one heart|
Heart capsules are the second type of capsule in Knuckleheads.
Heart capsules have the appearance of a usual capsule, only a spinning red heart is placed in the middle of it.
Heart capsules are much rarer than star capsules, and appear usually in hard levels. Smashing these capsules will restore one heart unit to the angry heads' health.
