Card Captor Sakura - episode 13

 Sakura and her friend Maddison are at the local zoo on a school outing. They and the other students are enjoying what appears to be a warm sunny day amidst the multitude of exotic animals that zoos are commonly famous for. Armed with notebooks and writing implements, the students are assigned to write up reports about the readily observable fauna, which gives Sakura and Maddison a chance to explore their surroundings before deciding on a theme to write about. The pedagogic tour is abruptly interrupted by strange observations, which Sakura and Maddison link to a missing Penguim slide from the local park that they had seen earlier. It doesn't take long for them to realise that there is a Clow Card at work, one which dislodges inanimate objects and heavy animals by use of sheer strength. Consulting Kero reveals that only the Power card would be capable of such physical feats. in order to trap the card's spirit, Sakura has to physically contend with the strong magical spirit, but she'll need help to overpower the card's outstanding strength
