Jigglypuff (SSBU)/Up smash

Overview
An upwards headbutt. Functions as a decent anti-air and a kill move at higher percents, especially against light characters, but is barely stronger than Jigglypuff's up tilt and worse than all other headbutt-related up smashes. It's often considered to be one of the worst up smashes in the game due to its sluggish speed, small hitbox, and below average knockback.

Trivia

 * Due to the sourspot getting its damage increased to match the sweetspot in a patch, the smaller hitbox no longer has a purpose.
