Nigel Planter and the Chamber Pot of Secrets (S03E12)

While enjoying a round of golf, Billy, Mandy, and Grim unexpectedly cross paths with young wizard Nigel Planter, who is evading the sinister Lord Moldybutt. Together, they return to the School of Sorcery, only to repeatedly encounter Moldybutt, who ominously warns them to steer clear of the mysterious "Pot of Secrets" concealed within Dean Toadblatt's office. The twist unfolds as it is disclosed that Lord Moldybutt is, in fact, Toadblatt himself, using a disguise to deter Planter. Note: This title humorously references Harry Potter and the Chamber of Secrets.
