Critters

A Critter is a background character that does not normally cause harm or interact with the player in any other way, except in that it can be killed by players or mobs rather easily. They have very low health and serve as ambient wildlife in the world of Terraria. Some critters can be summoned by means of a statue, and otherwise spawn randomly in any environments that support them.

All critters can be caught with the Bug Net, which allows them to be combined with a Terrarium for caged display.
