Tiger Hunt is the first half of the sixth episode in the first season of Stanley (TV series).
When Stanley's family gets tired of him taking pictures of them, they encourage him to find something else to take pictures of. Stanley decides to play a hide-and-seek game with Elsie and takes pictures of her, but wants her to dress up in his old set of tiger pajamas. Elsie, proud of her fur, reluctantly agrees, but then goes off for a cat nap behind the furnace where Stanley can't find her. When Stanley loses the game of hide-and-seek, he realizes he's going to need to learn more about tigers, and by association, cats, in order to figure out the best way to locate Elsie.
Only Harry the dog sings the song about The Great Big Book of Everything in this episode.
