Rest

Rest is 's down special move in Super Smash Flash 2. When this move is used, Jigglypuff falls asleep for a little while, doing no damage if Jigglypuff is out of proximity with an enemy or opponent. However, if Jigglypuff uses Rest while an opponent is in contact with it (as Jigglypuff's entire body encompasses the hitbox), the opponent will suffer 18% damage and be launched with extremely high velocity and knockback. The attack comes out in one frame and in that one frame if Jigglypuff will have invincibility frames as well. The attack's hitbox is 25% smaller than its Super Smash Bros. Melee incarnation. The special effect Rest gives off makes it look like its Super Smash Bros. appearance.

Rest is one of Jigglypuff's most potent moves, and one of the most powerful moves in the game. This is due to not only the fact that it deals very high damage and knockback, being able to KO reliably at low percentages.

Space animal slayer
The space animal slayer is a combo that can be performed by against fast fallers like, ,  (although due to his slim sprite hurtbox makes it difficult to connect with), and  due to their very high accelerated falling speed. High fallers like, , and more are also susceptible to this, but they can escape it a little easier due their accelerated falling speed being lower. How this works is that Jigglypuff takes advantage of a character's accelerated falling speed and is able to combo into Rest by using up throw, up air or up tilt. However, there is no guarantee that the opponent will be rested due to them being able to D.I. away from Jigglypuff, but due to Jigglypuff's high air speed, this should not be a problem.

However, this technique is very risky to do because if Rest is missed, Jigglypuff will be left opened to be punished. Due to Rest no longer KO'ing around 50% or below, it being harder to hit with and the less amount of hitstun in v0.9b makes it all the more risky. Also it best to use this technique on high fallers on stages with a high platform like or Yoshi's Story. Especially against a character such as Link who's down air would most likely kill Jigglypuff at mid to high percentages. The top platform being there would allow for the opponent to land on it and go into a laying down animation, which forces them to tech or use their floor attack. This gives Jigglypuff enough time to read what they are about to do and follow up with a Rest.
