I completely did everything in Magical Racing Tour earlier today (it capped at 105%), and I must say the Pirates of the Caribbean map completely falls apart once you look at it any other way than the way you're meant to race it. In the case of the skeleton it's ever the other way around, but if you look at that side there's holes in the geometry:

Not pictured because I couldn't get a good angle: some pirates having a face on both sides of their heads.
