Teetering

Teetering is an animation that is naturally activated by standing near a ledge in Super Smash Flash 2. The character will automatically teetering back and forth over the ledge with a panicky expression. Due to not having ledges in Super Smash Flash; it was not possible to teeter. The effect can only be done when a player walks towards the ledge slowly. Simply landing near the edge does not count, and moving too quickly will simply cause the character to run off the ledge. Characters will teeter regardless of whether the ledge they are hanging over can be grabbed onto. Characters will stop teetering if they take any action(such as jumping, shielding or attacking.

Trivia

 * On the bottom platforms of Meteo Campaign; on the left side of the stage characters will teeter regardless if they are near a ledge or not, while they won't on the right side of the stage even if they're near the ledge.
