snuggletruck started out as smuggletruck but got denied by the Apple app store. So they had to kidify their game to make it more appropriate.

Original Description:

Quote:
Smuggle Truck is an over-the-top physics-based driving game where you must save your passengers by smuggling them across the border in the least amount of time. Tilt your truck, catch newborn babies, drive over armadillos, and rocket your way through hills, caverns, deserts, and forests to save the people!


Basically, in smuggle truck you are smuggling Mexicans across the border.
