, automatically triggered machine gun nests, and cannonballs. They advance in that way as far as towards the strongroom. There, Scrooge snatches the neutra-friction pistol and fires it at his money, making it behave essentially as a liquid. The Beagle Boys are disappointed when they discover that the money masses are too slippery to carry. They tie up the ducks, leave the beam pistols, and go out to create an opening in the vault's wall to allow the money to flow out from the Money Bin. At that time, the ducks exploit the situation, they free themselves from the ropes with the help of the beam pistols. Scrooge hurries to the roof terrace and shoots an anti-inertia beam at the tools the Beagle Boys are using to bust a hole in the wall, which makes their tools useless. At last the Beagle Boys catch on, and attack simultaneously with many bulldozers.

Later, Scrooge shoots the Beagle Boys with both beam pistols and then shoves them into prison with a flick of his finger. Back in the second Money Bin, Scrooge is getting all of his money flowing back inside. Donald reminds him about the deal, where Scrooge promised to give him as many thousand-dollar bills that he can hold if he can protect his money. Scrooge gives them to him, but because the money is still friction-less, the money simply flows out of Donald's arms and back into the vault.
