The Free Toy is a toy figure which comes in when you send in 99 box tops of Kelp-O. It only appears in the episode: Waiting. SpongeBob worked hard to get the toy and kept on eating Kelp-O and waiting for it. It has the appearance of a four leaved clover.
The toy is very small and its main color is green. It has huge eyes and it wears a purple shirt with a red button on top of its body. It is always smiling and it wears black shoes.
The toy "breaks" when you drop it, as shown by Squidward at the near end of the episode.
