Mechanical Mouse

The robot mouse was a robotic mouse created by Mordred that lived in the Castle. It was used as bait to attract Merlin, which will make him follow you.

Role in Super Villain Island
In the Binary Bard's dream, the mouse was recreated in a larger version with red eyes that would pop in and out of holes and grab you to take you away. But if you freeze time at the exact right moment, you can use him as a type of stool to jump above the barrier in your way.
