Nigel Planter and the Chamber Pot of Secrets is the 12th episode of the third season of The Grim Adventures of Billy & Mandy.


Billy, Mandy, and Grim are playing golf when they encounter boy wizard Nigel Planter again. Nigel reveals that he is unable to stay at Toadblatt's School of Sorcery because he is being hunted by the feared Lord Moldy Butt (with the mere mention of his name causing things to break). Nigel asks the trio to accompany him back to Toadblatt's and be his security. The gang arrive in Dean Toadblatt's office and find Toadblatt suspiciously acting kindly towards Nigel (as Toadblatt has previously made his contempt for Nigel known). Later that night, back at Weaselthorp House, Lord Mouldy Butt sneaks into Nigel's dormitory and warns him to stay away from the Chamber Pot of Secrets in Toadblatt's office. Lord Mouldy Butt attempts to throttle Nigel but is spotted by Mandy. He escapes, but leaves a strange powder behind.

As Mandy and Grim begin their investigation, Billy accompanies Nigel to school and stands guard outside Nigel's classroom, but Lord Mouldy Butt manages to sneak in and again warn Nigel to stay away from the Chamber Pot of Secrets. Nigel is summoned to Toadblatt's office, where Toadblatt informs him that he will have to leave the school as they can no longer protect him. As Toadblatt is saying goodbye, Lord Mouldy Butt appears from the Chamber Pot of Secrets, but Mandy reveals that it was a costume Dean Toadblatt had been using to terrify Nigel. Mandy reveals that the dust Lord Mouldy Butt left at Weaselthorp House was actually from a latex mask, and hair and fingerprints collected from Nigel's room matched that of Toadblatt.

Toadblatt confesses and admits he did it in order to get Nigel removed from the school. Nigel gains his revenge by shrinking Toadblatt to the size of a golfball, which Grim uses and ends up hitting Toadblatt towards a French restaurant. Just as Nigel claims he knew there was no real Lord Mouldy Butt (which causes Mandy's golf club to break), the camera pans down to the centre of the Earth where the real Lord Mouldy Butt vows to find Nigel
