The golden pot before stolen
The golden pot is a pot Wario stole from Luxeville in the opening cutscene of WarioWare (TM) Gold and is later revealed to be a toilet in the final cutscene of the game.
The golden pot was discontinued as a toilet and Luxeville installed a new toilet, which means Lulu did not need to do this at all, at the end, she is flipped upside down laying on the ground, angrily grumbling.
When revealed to be a toilet....
Lulu-"Yay! Serves you right! The people of Luxeville have been holding it long enough."
Wario-"Huh? What's that mean? Holding it?"
Lulu-"This pot....is a potty! It has been just cleaned and put out to dry when you stole it!"
Wario-"..........Uh?......Ahah....AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!"
Wario wears this as a crown during the final battle....
