The Rainbow Rock is a natural rock that was discovered by Clumsy Smurf which appeared in the episode "All The News That's Fit To Smurf". Its purpose was unknown until later on in the episode, after Reporter's reporting of Papa Smurf's discovery of a grove of super smurfberries in Creepy Deepy Canyon had sent Brainy and some other Smurfs to follow Papa Smurf, that it had the power to put its giant snapdragons to sleep if they were ever disturbed. When Brainy and the other Smurfs had disturbed the snapdragons and awakened them from their sleep, almost causing him, Papa Smurf, and the others to be devoured by the snapdragons, Reporter and Grandpa Smurf came into the canyon with the Rainbow Rock to put the snapdragons back to sleep.
