Critter

Critters (クリッター Kurittā) are recurring enemies in Cave Story, making frequent appearances in various locations throughout the game. They are also one of the first enemies to be encountered when the player starts a new game.
== Appearance ==
Critters seem to have a gelatinous appearance, with a round, uneven shape. They possess white round ear tufts. They have a small indent that separates their bottom part into two halves. Two eyes are prevalent at the top of their face area as vertical black lines. A short horizontal black line forms an implied mouth or nose below the eyes.
Critters are colored according to the location they are in. This indicates their attacks, as well as the amount of damage dealt to Quote.
== Combat ==
Critters appear to be at rest when Quote is quite a distance away from them. They are sometimes hidden behind signs or partly into the ground; such is the case with aqua critters in the Egg Corridor or Power Critters in Bushlands. In some cases, critters may notice Quote when he is directly below them, and will start to hop in his direction.
When killed, critters leave behind experience, hearts or, if the player has the Missile Launcher, missiles.
Contact with a critter will cause Quote to lose some health, and may also move him in an upwards direction. This may be used by players as a way of boosting Quote up a ledge unreachable by jumping, like the passageway to reaching the Arms Barrier in the Labyrinth.
=== Attacks ===
A critter's attack depends on its type, denoted by colour and location. Most critters, when approached, move by hopping in smaller increments towards Quote. Others may be capable of shooting bullets or flying longer distances.
