Sunbeam's yellowness exceeds all expectations, taking into account that his color also reflects his cowardice. He is the last boss bear of Episode 7.
Sunbeam gazes at the stars in the night sky through his telescope when he finds an alien spaceship. He beckons to them in hopes of starting a friendship. His plan backfires and the Alien Bears invade the island, placing all of its inhabitents under mind control. He is found in the factory area with Emperor Xoon, the leader of the Alien Bears.
Sunbeam wears a tin foil hat in Episode 7. He is quite friendly and cheerful, gaining the friendship of all the other bears except Naughty Bear. He is also very cowardly when in danger. His sensitivity to naughtiness makes him very easy to drive insane and he usually chooses to flee or hide instead of fight.
