Wobbling
Wobbling is an infinite grab technique exclusive to the Ice Climbers in Super Smash Bros. Melee. Wobbling received its name during NCT2, where American smasher Wobbles claimed 9th place via the use of the technique. This technique involves grabbing and pummeling one's opponent with Popo, then repeatedly using the forward tilt or down tilt with Nana. This technique can inflict significant damage, and can lead to a KO if Nana performs a forward smash after sufficient damage has been inflicted. When performed with the right timing, opponents cannot break out of Popo's grab and will continuously get hit; the technique can also be used on all characters in the game except against another pair of Ice Climbers.
In competitive play
Due to its perceived overpowering potential, Wobbling is a controversial technique within the Melee community, and there exists considerable debate over whether the technique should be banned or not. Those opposed to the ban claim that Wobbling is too situational to pull off, as the only way for the Ice Climbers to easily perform the technique is for opponents to get quite close to them, reflecting poor matchup or gameplay experience of their opponent. Supporters of the ban claim that the technique is too powerful regardless of its supposed drawbacks as outlined by the anti-ban side; some tournament organizers also claim that Wobbling is an uninteresting technique to watch in matches, potentially deterring spectators from wanting to watch streams of games involving the Ice Climbers.
The most recent Smash Back Room ruleset for Melee does not have a specific rule dealing with wobbling; as such, it is generally up to the discretion of the tournament organizer to decide whether or not to ban the technique. Reflecting this, different tournaments have had different stances on the technique; the Big House and Epita Smash Arena series of tournaments ban Wobbling, for instance, while the Apex and Avalon series allow Wobbling.
Blizzobbling
Blizzobbling is a variation of Wobbling performed with Blizzard. Instead of a tilt, the partner uses Blizzard to damage the opponent while the leader pummels. When performed with correct timing, it can also be inescapable.
