I Spy is a play-along puzzle series based on the popular books of the same name. Spyler, Cece, Duck and Wheeler take the viewers into their fun-filled world of adventure. Puzzles and problem solving make this series fun for all kids.
The episodes start off with Spyler (who had a tennis ball head and button-shaped feet) 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.
