Kirby 64: The Crystal Shards/Enemies

The General Enemies
Enemies with no special power, so no benefit of gaining abilities.

Aquatic Enemies
These are also powerless enemies, but they are found in/around water.

The Power Enemies
These enemies have one of the 7 abilities Kirby can obtain by inhaling the enemy. It is also possible to spit out a power enemy at another power enemy to create a power combo.
