A day of new discoveries! Caillou loses his voice, finds a frog in his throat, and finds other neat ways to communicate, until the frog goes away. The puppets are also in on the discovery action when Rexy finds what he believes to be a magic Bauble on the ground. But when he finds out DeeDee lost her precious “thing,” Rexy magically returns it to her. Caillou, later on, is missing one of his favorite socks. He searches the house, and accidentally locks himself in the basement. Daddy comes to the rescue – only he locks himself in the basement too. All is well when Mommy saves them both and finds the missing sock. Rexy casts a few spells, Caillou loses a sock. The writers lose the will to write new segments and start throwing in segments from previous episodes of the new version of the show. In the puppet segments, Rexy finds what he believes to be a magic crystal ball and declares himself a wizard and starts casting spells with it. Meanwhile, Deedee is looking for her precious thing that she lost. Rexy casts a spell for Caillou, wishing that all of his friends will want to play with him. He also casts a spell so that Gilbert won't be bothered when he's taken on a car ride. Then, Deedee asks him to find her precious thing and he goes off to cast a spell. Deedee, however, follows him and praises Rexy find finding her precious thing. It turns out that Rexy's magic crystal ball was actually Deedee's "precious thing." Rexy realizes that he's a fraud, or is he? Gilbert and Teddy show and up and they're both very happy and Gilbert didn't mind his car ride at all. Meanwhile, in the Caillou portion of the show, it's lost and found and hit and miss as Caillou and his friends search for and find things that they've lost.
