From the Super Mario Wiki, the Mario encyclopedia
Lip's Stick is an item originating from the Japanese game Panel de Pon (localized as Tetris Attack in the West), where it is wielded by Lip. It makes a return in Super Smash Bros. Melee, Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS / Wii U, and Super Smash Bros. Ultimate, where it is used as a battering item. When a player gets hit by a Lip's Stick, a small flower would be planted on his or her head, doing gradual damage. Players hit continuously would cause the flower to grow larger, prolonging the duration it is present, thus causing more damage. With a strong or Smash attack, some magic shoots out of the item, slightly extending its range. Eventually this magic runs out, but players hit by the item itself will still suffer its effects.
