Ricky Wrench is an enlarged Rocky Wrench with the ability to dig from place to place that acts as the tower/castle boss of Mushroom Peaks in Newer Super Mario Bros Wii, it was a normal Rocky Wrench until Kamek used his magic on it.
Ricky Wrench is a Rocky Wrench that is roughly 4 times the size of an average Rocky Wrench.
Giant Rocky Wrench's arena has a sand covered floor, and a pillar in the center. Giant Rocky Wrench will dig into the sand, and pop up somewhere else, after coming up, he will throw big exploding wrenches in Mario's direction. Before he can escape, Mario must Ground-Pound on Giant Rocky Wrench's manhole covered head, causing him to retreat back underground. After every hit, Giant Rocky Wrench will come up from the sand on the pillar in the battlefield's center, with a large spike on his manhole head to prevent Mario from jumping on him, and throws his exploding wrenches in random directions for a few seconds before going back underground forcing Mario to repeat the process.
