The Mimicker Rebirth

The Mimicker Rebirth brings a redesigned Mimicer mob from Java to Bedrock, with new appearance, sounds, and adaptive behaviors that mimic players and environments.
When it sees you, it goes into animation and moves when you stop looking at it unless you get close enough to it.
His appearance is the same as Steve. He can appear in caves and forests. He doesn't like it when you hit him.
