Cardcaptor Sakura

Sakura's class is on a field trip to the aquarium. During the penguin show, something catches the trainer's leg and a penguin and pulls them into the water, but they are saved by Sakura's brother, Toya, who is working part-time there. At school, Tomoyo gives Sakura and Cerberus mobile phones and on the way home, Sakura bumps into Yukito who invites her on a casual "date" which is at a cafe where Yukito knew Toya was working. While they are eating, The Watery breaks the glass of the aquarium causing a flood. For the first time Sakura has to formulate a plan to capture a card, rather than jumping into battle and attacking with Windy. Using her wits and an unintentional clue from Yukito, she lures Watery into a freezer to immobilizes and capture it.
