you get it when you defeat all the villans then answer the phone
In Poptropica, if you wanted super powers, you need to beat the first five villains (Sir Rebral, Copy Cat, Ratman, Crusher, Speedy Spike) and then go to the Telephone Booth, where you answer the phone by clicking it twice. You now have super powers. You use them to beat Betty Jetty, who is on top a building Downtown.
Sir Rebral is one of the 6 super-villains on Super Power Island. He uses his mind power to control physical objects.
Copycat, Speeding Spike, Sir Rebal, Ratman, Crusher, and Betty Jetty
This is a list of the easiest to the hardest villains to catch on Super Power island: Speeding spike Copy Cat Crusher Sir Rebral Ratman Betty Jetty is not the hardest, but must be the last. All you do is fly after her and dodge the green glowing balls for a minute or two, then run into her. (see related question)
