Yoshi Bomb

Yoshi Bomb, known in Japan as Hip Drop, is 's down special move in Super Smash Flash 2.

Overview
When performed, Yoshi flips forward and then shoots straight down rear-first, becoming very horizontally slim as he does so. He plummets at high speeds straight downwards, though his descent can also be shifted to the left or right. Opponents in his way as he plummets are dealt 9% damage diagonal knockback upward. When he lands on the ground, two stars will appear on either side of him, dealing 4% damage to opponents hit. When used on the ground, Yoshi will also perform a high jump forward before falling, dealing 4% damage to opponents in his way as he does so.

Origin
Now known as the Ground Pound, this move has become a somewhat standard move in both the Mario and Yoshi games, originating in Super Mario World 2: Yoshi's Island. In this game, Yoshi performs the move almost identically to how he does in SSF2, as he flips forward before plummeting to the ground. He could use this to pound down stakes, crush crates, slam through soft dirt, and of course, damage and defeat enemies. Yoshi's animation during the midair descent is modeled after the Ground Pound from Yoshi's Story.

The stars produced by the move are original to the Super Smash Bros series, though they may also be a reference to the stars produced by many ground-smashing attacks in the Kirby games.
