Legends of Spark Season 1 Episode 21 Ice Pickup

Spark and his friends are training in the snow in order to help Bolt, who has mistakenly driven up the snowy mountain and has run out of energy. Bolt suggests that a blue flame could help replenish his energy. Spark and Bellows go looking for it, and run into one of Snowblind's trials. During the trial, Bellows is trapped in an ice cube, and Spark exhausts the last of his energy to save him.
