- Crushed truck
Get the shrinker power-up. Then, shrink your opponents and crash into them. When they become large again they will be crushed. Note: The trucks will only be crushed for a short period of time. They will slowly regain their original size.
- Big tires when hovering
Note: Two players are required to perform this trick. Have player one get the hover power-up and player two get the shrinker power-up. Then, have player one use the hover and begin to fly. While player one is in the air, have player two use the shrinker. The truck will shrink but the tires will remain the same size.
