How do you defeat the villain throwing rocks on super power island?

Sir Rebral is destroying the statues in the park with his telekinetic power.

When he throws a chunk of rock at you, jump next to him so that it hits him instead. Then he will start pulling up the ground to hit you. Push the rock from near the restroom over to the left, a bit right of directly under him. When he pulls up the ground, the rock will knock him out.
