He sent it to a snow topped mountain to recover the Lunar Locket. When the Xiaolin monks attack him but he manages to hold them all off with lasers, magnets, and just brute strength. While he fends them off he keeps making attempts to make them his friends. When they deny him however he gets really sad, starts to cry, and throws the Heart of Jong off a cliff stating he doesn't want to be human anymore. Jack however manages to get the locket.
