I thought it was Henry VIII's Great Seal. Guess I was wrong. 
Orange and Purple lost at the moat, not steps of knowledge in Great Seal.
Anyways, here's my next question:
The Green Monkeys and Purple Parrots were 1 and 2 in the moat.
The frontrunner only lasted 3 rooms.
The second runner made one of the biggest mistakes in the shows history.
