Power Up:
On level 1, start by going down then to the far right where there is a sewer. Enter it 
and surface on the other side. When you resurface enter the only optional sewer which 
blocks you from the rest of the level. Enter it and you will see a pizza, grab it and 
exit, then return and it will be there again. Repeat as needed.

Note: This works anywhere you find a pizza. 

Eliminate the Roller Car
In Level 3, if you're riding in the Turtles' Party Wagon and there is a Roller Car on 
the screen, press Select to get out of the Party Wagon. The Roller Car should dissapear.
