Horse isle 3 riddles. To defeat the alien abduction level all you have to do is get past all the aliens use helium homer to blast across the valley and pull the trigger and then use homer ball to blast across the other platform and land on the platform then pull the trigger again and a ufo should take you and bart into it and release the guy that is an orphanage dude and pull the trigger to release him and then use homer ball and blast all the alien releasers and you should be done with that level and you should unlock the video game level and defeat Matt Groening. To defeat the evil donut boy all you have to do is pull out bart's slingshot hold down l1 and press circle and be careful he might charge his laser at you if you do it correctly there should be a hatch open double jump bart and dislocate his wires by triangle and use the same routine except use double jump with homer and for the third time get on a high ledge like the construction zone or on top of krusty burger or something tall and make sure your normal bart and double jump him and while your in the air turn into bartman and make him glide and undo the hatches I spent 12 hours to figure out.
