Sakura and Double Trouble Kadokyaputa Sakura : Season 3 Episode 12

Eriol casts a spell on Kerberos and Yue so that they are unable to revert to their guise forms, much to Sakura's dismay, since it is understandably difficult to hide their true forms for long. Fortunately, Toya and Fujitaka are out for the day, and Sakura has them help around the house while reminiscing about their time with Clow Reed.
