Patrick's last baby tooth is hurting himself and he goes to the dentist with SpongeBob. The first time he goes there, he exits nervously after refusing to let Dr. Mundane take out his baby tooth. The second time, after SpongeBob telling him about the tooth fairy, he goes again and Dr. Mundane extracts it without any pain.
After Sandy gets a teeth cleaning here, SpongeBob tells her that Gary can talk. Sandy says she invented a device that makes nuts talk. She says that walnuts are extra nutty.
