"Tree Trunks" was written and
storyboarded by Bert Youn and Sean Jimenez from a story by
Merriwether Williams and Tim McKeon, and directed by
Larry Leichliter. Although the episode was the fourth aired, it was really the sixteenth produced; this is why Tree Trunks appears in the later
season one episode "
Evicted!" despite her vanishing at the end of this entry. The episode features the introduction of the titular character, played by Polly Lou Livingston. Livingston was a friend of
Pendleton Ward's mother Bettie Ward and knew Pendleton when he was a young child. After having not seen her for eight years, he approached her, asking if she would like to play the voice of a character on
Adventure Time. She noted that she "nearly fainted" when asked and was surprised he still remembered her. Thus, this action was the genesis for the
season two sequel "Crystals Have Power", which saw the return of Tree Trunks. The unedited version of the episode, featuring Tree Trunks simply exploding, was featured, however, on the
Adventure Time: My Two Favorite People DVD. Episode composer Casey James Basichis used a variety of basses and saws to create the whimsical music featured in the episode. He later called the resulting sound a "folksy massacre". ==Reception==
