Lip's Stick originates from the Japanese puzzle game Panel de Pon, where it is held by the game's protagonist, Lip, on the title screen and in the background of puzzles. In-game, Lip's Stick is referred to generically as a "flower wand" (はなのつえ).
In Panel de Pon's Vs. Mode, when performing a combo or clearing more than three panels at the same time, a symbol flies over to the opponent's side, immediately followed by the appearance of a garbage block. If the player is playing as Lip, she waves her flower wand at the opponent when this occurs, and the symbol and garbage block are flower-themed. The flower's continued-damage property in Smash may be a reference to the garbage block's interference to the opponent's gameplay.
Lip's Stick is classified as a battering item, with the unique side effect of inflicting the flower status upon any fighter struck by it. Tilt and smash attacks cause the item to release "dust", which similarly inflicts the flower effect, but deals less damage and knockback. Repeated use of Lip's Stick and its dust causes the flower to grow, making the effect last longer. However, the item has a limited amount of dust; once it runs out, Lip's Stick can no longer attack from a distance, but can still be used as a battering item. Furthermore, the dust is considered a projectile, and can consequently be reflected and absorbed.
This magical stick was used by the character Lip in the Japanese game Panel De Pon, which was later released as Tetris Attack in the United States. Lip's Stick causes a flower to sprout from an enemy's head, inflicting damage as it grows. Quickly tap the Control Stick back and forth to get a flower off of your head.
Lip's Stick was first confirmed to return in Super Smash Bros. Brawl when it was shown in a Smash Bros. DOJO!! update concerning Munchlax, behaving the same way as it did in Melee. It can not give the flower effect to the Fighting Alloy Team, although it still deals a considerable amount of knockback when used on them.
An item that causes a damage-dealing flower to bloom on people's heads. If you find yourself with a flower on your noggin, start rattling the Control Stick back and forth to shake it off. Some characters can pull off having flower-covered heads in style, while others clearly cannot.
Lip's Stick returns as an item in Super Smash Bros. 4, acting as it did in Melee and Brawl. The damage it deals is now classified as a magic attack, creating sparkly effects with each hit. The equipment of the same name allows the player to equip the item at the start of a match.
Lip's Stick returns as an item in Super Smash Bros. Ultimate. Additionally, its appearance is used as the basis for the Mii Swordfighter's sword when wearing the Lip Outfit alternate costume.
