Mecha-Turtle

Mecha-Turtles are enemies in Mother 3. They have powerful cannons under their shells, which can only be fired when their back is facing the party. In order to use this ability, Mecha-Turtles turn themselves around when encountered from the front and are the only enemy besides the Whatever to do so. When encountered from the front, they will not attack unless they receive damage beforehand.

Battle Memory description
Even this provincial tortoise was built into a fighting machine, but it's still as slow in the head as ever.
