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 enemies 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. If a Critter caught with a Bug Net is taken from the inventory and "used" (placed on the ground), it is again released into the environment to behave as usual. Many caught Critters can also be combined with a Terrarium to make a Cage for display. In the case of Butterflies, a bottle is used instead to make a Butterfly Jar, or Bottled Water in the case of Goldfish. Bottled Fireflies and Lightning Bugs also function as light sources.

Many caught Critters can be used as Bait with a Fishing Pole in order to go Fishing. These generally include any insect, worm, or mollusk (snail) Critters.

In total, there are 28 critters: 11 vertebrates, 17 invertebrates.

Tips

 * With several NPCs acquired, keeping Water Candles around your Town will cause more Critters to spawn, without spawning enemies.
