Mechanical Mouse

The Mechanical 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. You need the moldy cheese from the dungeon to obtain him.

Role in Super Villain Island
In Binary Bard's dream, the mouse was recreated as a slave just like Merlin, similarly in a larger version with a red color scheme instead of turquoise. It would pop in and out of holes and grab you to try and take you away, just like the Merlin in Binary Bard's dream. 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.

Trivia

 * The Mechanical Mouse was included in the Super Villain Island Members-Only Evil Henchmen bonus item.
