Sunflower

Sunflower is the subject of the episode Flower Power!. He was depicted as an anthropomorphic Moon-Walker sunflower. He was put on the windowsill where Orange was, greatly irritating him as he was trying to tan. After a while, Orange began annoying Flower, who was eventually cut off his stem, giving Orange his sun back. However this was short lived, as Flower came back in a bouquet. However, he was killed by a swarm of bees seconds after. He later appeared in Annoying Orange Comedy Roast and Annoying Ways to Die.

Trivia

 * His cultivar is Moon-Walker.
