Sakura and the Panicky Bike
Sakura learns that the Clow Cards she is unable to use are beginning to lose their power, and will become ordinary cards if they aren't converted into Sakura Cards. Unwilling to let this happen, Sakura brings her Star Wand and despite Kero's misgivings, recklessly converts several cards at once although she's left weakened. However, she loses control of one of the cards, the Dash, which panics and flees, possessing Toya's bike which Eriol had enchanted earlier while helping Sakura clean her yard.
