The Simpsons Game Strategy Guide for the Wii 8: Around the World in 80 Bites, Part 3
There is a giant pizza here, and Homer needs to roll as Homer Ball on the slicer/spatula to hit the meatball on top. You do that by flicking the Wiimote, and a piece of spaghetti is revealed.
Bart needs to climb the spaghetti, then take the ladder to the right. He then needs to double jump to the next ledge up.
Bart will soon be at an area that looks like the Roman Coliseum. There is the Fifth Krusty Koupon on the top of that next level. Bart needs to actually run the way opposite that Krusty Koupon, and soon he will find a ladder that will take him to that level. He will then need to jump the gaps and get to that Koupon.
By the way, sometimes these gaps are harder than they look, and it took me several tries before I got them. You might want to keep your eye on the timer to see if you have the time to get it. You might be able to get it later if this is the case.
As for the last Koupon, you will need to climb to the top of the Golden Gate Bridge via vines. If you look to your right, you will see the Sixth Krusty Koupon located on a ledge nearby some large Duff Beer Vats. Glide down to it and claim the last Krusty Koupon.
Now, retrace your steps back to Italy, and work your way to the bridge, climbing it until you reach the top. You will see a lever down below. Soar there until you land on the lever, or over it. You can climb a ladder from the other side to the top, and open the door to Americaland.
You will notice a Statue of Libery come up, who is surrounded by dancing girls. What you need to do is get Homer to the top of the platform (the one that looks like a quarter). Turn him into a Homer Ball, then launch him toward the light (the glowing part, not the torch) on the Lady Liberty.
The Dancing Girls will retract, and Homer needs to hit the Statue one more time. Do this before the Dancing Girls come up again, which will not take long. The Statue will sink down, and the dancing girls will come back.
Hit the one sweet spot (the one that is glowing) again, then hit Liberty again after the dancing girls go down. The Statue of Liberty will go down again. Get on the platform, and give the dancing girls another hit with a Homer pound. The Lady will drop the hamburger.
Roll into the Homer Ball onto the Hamburger, and this level will end.
