Snappy brought the dinosaur home to the Smurf Village and treated him like a pet. Although Crinkles was rather careless in wrecking parts of the village, he did not do so out of spite, instead being unfamiliar with such an environment. Unfortunately, Crinkles fell sick because he was unable to eat the food of the present time.
With the help of Grandpa Smurf and his time crystals, Snappy and several other Smurfs went back to the prehistoric period to bring Crinkles safely back home to his family. Crinkles' family returns the favor later on, when the Smurfs are kidnapped by Grog. Crinkles and his parents attack Grog, allowing the Smurfs to break free.
