Butterfly

Butterflies are animals that appear in Sonic and the Black Knight.

Physical Appearance
The butterflies have black bodies and black wings, though these wings gradually change to a purple color.

Overview
Butterflies affect the player in a way similar to the Bats, only doing so when the player gets near them. When this happens, they surround the player and use some sort of magic that causes the player to fall into an illusion, making them see things that aren’t around or to not see things that actually do exist in reality.
