Betty Jetty is throwing green swirly fireballs at you, in sets of four or just one. If you get hit by six of them, you'll lose your flying power temporarily and you will have to re-start the chase.
Stay far back from Betty Jetty until she has launched about 6 or 7 sets of balls. This will take about a minute or two. Then you will be able to get close enough to knock her down.
Betty Jetty's not on TimeTangked Island she's on Super Power Island
The hero who defeats Betty Jetty will receive the Island Medallion! (hmm...see the related question)
There are no weapons on the island. Betty Jetty can throw energy balls at you.
You Have to defeat all the villains on super power island except Jetty Betty.
She can be found either the Super Power Island or Reality TV island (sometimes)
Defeat the other 5 super villains (all but Betty Jetty). When you walk past the telephone booth, it will ring. Answer the phone and you will be given the power to fly. Now you can go after Betty Jetty, on the skyscraper Downtown.
Open the booth when you have beat all the other villains besides Betty Jetty. Then you should get the power to fly and put Betty behind bars. :)
When you chase Betty Jetty, stay back from her so that you can dodge the green glowing spheres. You only have to chase her for about 2 minutes before you can get close enough to run into her.
You have to beat all 5 of the other villains to get to Betty Jetty because once you defeat all the other villains you get your powers and you can fly. (see related question)
Once you have captured Betty Jetty, she joins the other five villains back in jail. The warden tells you that Ned Noodlehead received the Island Medallion (he tackled Betty Jetty, after all). Go to the comic store and talk to him about it.
At the end of Super Power Island, you go to the phone booth. (click on it) Then, you will get flight!!!!!!!!! You have to defeat Betty Jetty!!!!!!!!!
Hide in the screen you'll win pinky promise
