Butterfly

Butterflies  are small  Mobs  found throughout the  Overworld  and in a few other  Dimensions. Right-clicking on a Butterfly sends the player to the Chaos Dimension. Right-clicking on a Butterfly while in the Chaos Dimension will send the player back to the Overworld.

Summary
Butterflies are found flying around areas or around Butterfly Plants. They are normally not aggressive, but a variant called Vampire Butterflies found in the Danger Dimension or spawned by Caterkillers will attack the player.

Containing a Butterfly can be done with a entirely sealed area with a Trapdoor for easy access and using a Zookeeper Shard to make a easy and local way to get to the Chaos Dimension.

How to Kill
A Vampire Butterfly is aggressive, but can easily be killed in anyway. A large amount, like killing multiple Caterkillers, can be killed with a Thunder Staff or a Attitude Adjuster.

Mod From
Butterflies are from the Orespawn Mod.
