Body Slam

The Belly Flop Attack is one of Crash's moves. To perform it, you must jump and press the duck button while in the air. Crash will slam down and crush anything beneath him.

Uses
The Belly Flop can destroy Locked Crates (although the Super Belly Flop is needed to do this in Crash Bandicoot 3: Warped). Other than that, it doesn't have much uses.

Power-Ups
The Belly Flop's Power-Up is the Super Belly Flop. It increases the Radius of the Belly Flop by 2 or 3 crates. In the Wrath of Cortex, it appears as a secret Power-Up, obtainable in Banzai Bonsai's Death Route.
