After a Rocky Wrench is defeated, there will be another that returns, before being stomped on.
 Super Mario Galaxy
They would return in Super Mario Galaxy on the Gusty Garden Galaxy and the Battlerock Galaxy. They will throw wrenches like before but if Mario is close to the trap door of the Rocky Wrench, it will not jump out. It will only jump out if Mario is a short distance away.
