Jack's induction to the Guardians

History
During the first time, Jack Frost was chosen to be a Guardian of Childhood by the Man in the Moon. Jack was kidnapped by Bunny and two other Yetis. When Jack asked why he was there, North attempted to inaugerate Jack into the Guardians, however, he reacted by slamming his staff onto the ground, causing a blast of ice and snow in the room.

However, in a second attempt, after the war with Pitch Black finally ended, the Guardians and Jack were victorious. During this time, North, asked Jack if he wanted to make it official now, with one of the elves from Jack's first induction,  glaring at the situation. After North delivered the Guardians' Oath, Jack, on inspiration from his believers, accepted the oath, North proudly called Jack an official Guardian, much to the delight of his fellow Guardians and friends.
