Tummi decides to create a bee-caller to pollinate the gummiberry bushes faster so harvesting will speed up. But he creates it wrong and doesn't bother to fix it, and ends of attracting an army of beevil weevils instead, who destroy every single bush. To make up for what he's done, he takes a dangerous journey to Fangwood Forest to find another plant. Gusto joins him and they discover the forest is occupied by a trio of talking trees who hold a grudge against the Gummi Bears. They escape, but the oldest three and Artie are captured when they come looking for them.
