Jelly fish from an old episode of Sesame Street, while swishing up and down said "Yop Yop".
Oh, Big Bird stick your beak under water and look at the jellys going "Yop Yop, Yop Yop"...

Yop yop means that Alder stole this from Christa, and claimed it as his, which would mean that Alder is a stealer face and this word belongs to Christa, therefore Christa wins no challenge.
Yay for yop yop! :)
