Rollout

Rollout (ころがる, Korogaru, literally "Roll")  is Jigglypuff's down attack in Super Smash Flash and standard special move in Super Smash Flash 2. Jigglypuff curls into a ball and rolls forward, ramming into opponents while saying "Jigglypuff!". In SSF, the attack functions similarly to all of the other rolling attacks in that game. Jigglypuff shoots forwards, hitting her opponent(s) multiple times, but she can't turn around like she can in the official games. In SSF2, the move was changed to more closely resemble the real move, thereby allowing her to charge up the attack and turn around mid-roll, at the expense of losing its multi-hit property. The move deals 7-14% damage with vertical knockback. When Kirby uses this move, he will say, "Purin", Jigglypuff's japanese name.

Origin
First introduced in Pokémon Gold and Silver, Rollout is a Rock-type attack. If the user has already used Defense Curl, then this attack's base power and its 5-turn intensity becomes effectively doubled. It is one of the most powerful Rock-type moves in Pokémon.
