Objective: Get Homer into Australia
---------------------
Run up the ramp on the right side as Homer to the edge - once there, transform into a ball and use your burst ability to cross the gap into Australia.
---------------------
Objective: Take Homer to Mexico
---------------------
Head down the ramp (in the red wall) to enter Mexico.
---------------------
Objective: Smash the Super Taco
---------------------
After entering Mexico, turn left to find the Super Taco on the left side of the giant Duff Beer ad. Use Homer's Ball Boost to burst through it and land in Mexico.
---------------------
Objective: Open the gate and take Homer into Scotland
---------------------
Proceed up the ramp ahead into France. Now use Bart and climb the ladder behind the Eiffel tower. From there, leap onto the umbrella on the right to bounce into an updraft - use your cape to sail up to the nearby rooftop.
Now grab hold of the zipline overhead and ride it over to the Eiffel tower. Press the button near the lift to ride it to the top. Once there, use your cape to glide to the large "X" below, on the wall bordering Scotland and France. Now run left along the wall and activate the switch to open the gate, allowing Homer to enter Scotland.
As Homer, run up the grassy ramp (right by the gate you just opened) and ball boost into Stonehenge to knock it down, allowing you to get past. Now jump aboard the bagpipes and pound them into the ground to blow air out of the vents.
Now switch to Bart and hop into the bag's venting air. Use your cape to land on the wall ahead, separating Scotland from Italy.
Use Homer to boost ball up the handle of the pizza cutter and bash into the meatball above to destroy it (this may take a couple of tries), revealing a rope that can be climbed.
Climb the rope up the ledge and head right, up a couple of raised platforms to another ledge. From there, head left, then down a ramp onto the Golden Gate bridge.
Use Bart to climb up some ivy growing on the bridge's right side, and climb onto the top of the bridge. Use your cape to glide to a switch below, just right of the closed door. Activate it to open the way into America.
