The Solemn Gorg Oath is used for situations with serious significance to the Gorgs. The oath is taken by all members involved in the contract by holding up their right hand and repeating the words of the oath: "Hey Nonny, Nonny, Nonny, Hey Nonny, Ha Cha Cha!"
Unlike The Solemn Fraggle Oath, The Solemn Gorg Oath is a permanently binding contract that cannot be broken or released, even in the case of fraud. The only way to reverse it is for all parties to swear to a new counter active arrangement.
Episodes in which the oath is used include:
- "Junior Sells the Farm" — Junior sells the Gorg Castle to Wander McMooch for the Peas of Power. Junior swears the solemn Gorg oath that McMooch will receive the castle, but learns too late he has been defrauded.
- "Junior Faces the Music" — Junior swears the solemn Gorg oath to "The Shadowy Figure" that he will play the Royal Kazoo in front of five Fraggle witnesses when the Blue Moon is full.
