We start out in Scrooge's main office, where Donald's busy cleaning (and griping about it because the ladder he was given to clean the light fixtures seems nearly as old as Scrooge himself). He takes a tumble and lands behind the reception desk, where Scrooge asks him to also fill in for the secretary who's away.
What ensues is a long, long stream of shenanigans involving the fact that up for them is horizontal for us, which includes plenty of falling sideways and getting tangled up everywhere. First hurdle, however, is how to climb out of the office and catch Magica, when they can't walk on the floor anymore.
By using the fallen ladder, some money bags, and other items around Scrooge's office they're able to construct a "tower" and get out the door, which lets them access the stairs that they can more or less use normally. ...And pass poor secretary Miss Typefast on the way out, making her wonder once again why she took this job in the first place.
The boys run into the nephews, who provide them with a solution that works for a.... little while, and randomly results in one of my favorite panels, of the two of them banging together on either side of a tree.
The nearby water provides yet another answer (and another of my favorite panels, in Scrooge's INEEDYOURUMBRELLAKBYE bit), and after hitting the bus sign they decide to wait for the bus to get to the airport.
They get to the airport (with the bus driver now questioning why his life/job), fly through the bus and out of it, and Which if you ask me, "It takes more than the disruption of the basic laws of physics to thwart Scrooge McDuck!" is one of the best lines ever.
But now with their gravity turned another 90 degrees, if they go outside they'll fall up, up, UP into oblivion. But the nephews have tracked their magically maligned uncles to the airport, and come up with another idea.
So, thus concludes A Matter of Some Gravity. It's one I found only earlier this month (as it wasn't printed in Uncle $crooge at all), after coming across this panel by itself AND WONDERING WHAT THE HELL WAS GOING ON
(Incidentally I want to point out a couple references here. One, Donald's mug. Two, the Beagle's words in the second panel of the second page, which is foreshadowing to a different Rosa story, and one I'll also cover in the future. But for now, I just wanna call your attention to it 83 )
Donald scurries out with his GENIUS IDEA and returns with a great startle panel from Scrooge later with a genuine Gearloose invention. Which is our first indication things are about to escalate quickly.
Seems the invention detects threats around the space of the Money Bin, thereby giving Scrooge a heads up and a way to defend. First threat! Arpin Lusene, a pastiche of exactly who you think, who's appeared in two of Rosa's other stories intending to steal from Scrooge just for the sake/fun of it.
Arpin's put down about the quickest he's ever been repelled, we get a great panel of Scrooge watching an explosion (and I randomly love the next of the ducks watching him fly), and Scrooge gets back just in time to hear another threat over the radio.
Spies from distant brutal country of Brutopia (which first appeared in some of Barks' stories, I believe) are about to launch an assault on the Money Bin, but Scrooge gets to them first, we get the page from the vote, and Scrooge gets to hear another threat.
I've said it before and I'll say it again, Scrooge's treatment of Donald, particularly in Rosa's stuff, is a little rough sometimes, but I think this is one time I'll give Scrooge a point. And hope Donald went into hiding for about six months after this.
Bonus story! Same issue of Uncle $crooge, follows directly after this one. I've plurked it before but I'll do it again, it's only three pages. Debt to a Salesman by Pat and Shelly Block, drawn by Pedro Alférez Canos and first printed in Denmark in 2001.
