I'm sure she could, but it would be very wasteful of energy. I was once challenged to demonstrate that I could swim 50m wearing a 4.5kg diver's weight-belt without a wet-suit or any other buoyancy/swimming aid. The weight was easily sufficient to allow me to stand on the bottom of the fresh-water swimming pool; flat-footed, completely submerged, with full lungs. I had no difficulty passing the test, but I had to work much harder than normal to stay close enough to the surface to breathe. With sufficient power, I'm sure Momo could swim, but the battery drain would be much greater than just walking along the bottom.

This is the kind of thing that I'd tend to assume pretty much everyone knows...
Anyway a fun and simple experiment to show the phenomenon to kids, is to put an raw chicken egg in fresh water: it sinks (hopefully - if it doesn't, it means it's rotten). Add salt to the water, the egg floats.

In the event of a water landing, Momo may be used as a flotation device.

Did you mean that ironically?
Redball:
You wouldn't think of her as pneumatic.
