I think about 12
to avoid betty jetty's green balls just don't fly into them and fly around th green balls.
you don't trow them you avoid from being thrown from you
no they go right through her
Flying in pursuit of Betty Jetty, you must dodge all, or most, of the glowing green energy balls that she tosses at you. If you are hit by 5 of them, you must restart the chase. To keep from being hit, stay away from Betty for the first 5 or 6 SETS of green balls (either four balls or one ball in a set). Move rapidly left, then right, when the balls come at you, ducking around or between the balls. After 6 or 7 sets of the balls, you can quickly run into Betty between sets, and knock her from the sky. (see related question)
Stay far behind Betty Jetty so you can avoid multiple balls. After six or seven sets, you should be close enough to knock her down. (see related question)
Hide in the screen you'll win pinky promise
You should stay well away from her to give yourself time to dodge (hard to the right or hard to the left will usually avoid the energy balls). After 6 or 7 sets (either one or four balls) you can get close enough to knock her down.
go to the side and avoid them
There would be four balls in the six groups
First, dodge the green things. When you get close enough to Betty Jetty, Ned Noodlehead will come and save the day!
Follow her and avoid her attacks.
You need to beat all the other super villains then go the telephone you'll get flying power then you follow her watch out for the green lava balls.
