Tony Hawk's Underground 2: World Destruction Tour Cheats

Still cat
In the skatopia level, get smokebombs and go over to the purple cat and have it attack you. Then, while it's on your head, throw a smokebomb and the cat will go completely still. Make sure you hit the cat. The cat will stay on your head even when you do tricks. After a while, the cat would start walking in place. To get it off your head, go to where the cat was originally and run into the trailer.
