Great episode. I loved it. It was the first Quack Pack ep I saw. Daisy's dangerous stuff were pretty freakin' cool.
So, Ken Powers uses Bobo, a small sized gorilla, to do the stunts for him. The exchange? A banana. Then, Donald's newphews accidentally write over the tape, and they go re-record it all over again, with themselves. Donald and Daisy saw the tape, they told Ken Powers that he won the stake and they left. But, Hewy accidentaly played a part of the old tape, which clearly shows what happened! They tell everything to Donald and Daisy, and they get hired back ;)
