I Spy is a stop-motion/claymation television series that aired on the HBO Family digital cable television channel and Qubo in the United States from April 2003 to January 2004, based on the popular children's book series drawn and written by Jean Marzollo and Walter Wick. Produced by The Ink Tank and Scholastic, the show lasted for 26 episodes.
The episode starts off with Spyler (who had a tennis ball head) and CeCe (who looked as though she was made of blocks) trying to find something to do. When they find something, they discover that they need different items. Duck arrives and gives Spyler and CeCe four (or sometimes three) items to find, which she says in a rhyme. Spyler and CeCe then start searching for the items. After each item is found they sing their "Whoop! We Found It!" song. Duck arrives again and tells them what they have found and what they need to find in rhyme. Spyler also calls for Wheeler to take their stuff home. After all the items are found, Spyler and CeCe do their activity/task. They always find a use for every item.
