"You Ain't Seen Nothin', Yeti" is the eleventh episode in the second season of The Wild Thornberrys. It is the thirty-seventh episode overall.


To study and protect the snow leopards from extinction and a construction site that is threatening their survival, Nigel's mentor (thought to be lost for many years) has left civilization to be a yeti.

Eliza discovers his identity, helps him fend off the construction workers, and reunites him with her father.
