xx

ok first hit the stone thing with homer ball and then make homer slam on the bag pipe  and then get bart to glide on it to get to the switch.

BartWill Wright wants to destroy your retro counterparts, and even though they deserve it for atrocities like Bart vs. the Space Mutants, you have to help them anyway. Jump onto the platforms and hit the first target with your slingshot. When you reach the flames, wait for them to subside and use the torch as a leaping pad for the grappling hook. Swing across and jump on and off the next pad without stopping. Pull the lever to switch to Homer.

HomerProceed right with Homer then stop short of the ramp. Dash into the ramp in Homerball form and you'll land on platforms at the top. Get out of Homerball form and jump off the platform to the right to get the Duff Cap nearby. Hit the button

BartUse Bart to cross the torches and hit the next lever.

HomerWhen it's time for Homer again, use the Helium tank to get up to the button on the top right.

BartUsing the steam, get to the last lever to end the level.

1. You must now cross the chasm. Step on the left pressure pad to trigger the ledges. Have Bart climb the ledges that project out and then have Homer step on the right pressure pad to trigger the other ledges. Once they are out, have Bart climb to the top.
2. Tip: If Homer steps off of the right pressure pad while Bart is on the ledge, the ledge will recede and Bart will fall.
3. Once Bart is at the top of the statue, turn him into Bartman and jump to the platform in the center of the chasm. A bridge will come out for Homer to cross.

Oh, and please don't forget to give this solution a fixya rating.

Ahh yes tricky, once groundskeeper willie jumps to that bit to acess the next country you must change to bart and do a mini course,climb a ladder,jump up onto a platform, then take a flying fox across toward willie onto another platform and take a BIG jump over the wall and let the bridge down!

Get homer on the Dino then Bart then change Bart into Bart man so he can go to drop the bones on pohlp and homer wil come to the door then get homer trough tthe door
