What do you do if you are stuck in the sewer on super power island?

The phone will ring once you have captured the 5 super-villains (Copycat, Speeding Spike, Sir Rebral, Ratman, and the Crusher). As you pass coming from the prison, answer the phone. This will give you your super flying power, which is toggled on and off by a small icon at the bottom left of the screen.

Go to the skyscraper and climb up to chase Betty Jetty. After you follow her for about two minutes, you will be able to get close enough to knock her down. Avoid all the green glowing balls she throws at you.

(You get some help from Ned at the end. See him at the comic store and bring a hot dog.)
