Jack Frost is a character that appears in the Season 6 multi-part episode "Smurfquest". He is the ice elemental who guards the pure water sample needed to restore the power of the Long Life Stone in the Arctic circle. He was awakened by Sassette when she snapped off an icicle, who then pursued her and the other Smurfs until he froze them in ice with his icy breath. However, when Gargamel entered the cave and disturbed Jack Frost, he accidentally caused the Smurfs to be freed from their icy prison. Originally, Jack Frost thought that his visitors, the Smurfs, were out to destroy him, but when he realized from the Smurfs that that wasn't their purpose, he allowed them to take a pure sample of the water element and go on their merry way.
