In the anime
Boatchi first appears in episode 19, part 2. He was found under some pillars and was freed by Mametchi and his friends. He explains that he accidentally knocked into the pillar, causing it to fall on him. He did that because he was excited that he was going to be with the girl of his dreams. Although being dismayed several times, he soon reunited with his true love, despite her being cross with him about disappearing. The two floated together and disappeared.
