You wouldn’t be able to make detailed shapes from a round balloon, like in the comic, but if the balloon was already shaped like a horse when deflated, it might be possible
I think with enough R&D into specialized balloon-manufacture techniques, it would be possible to make round balloons that inflate into a different discernable shape. But it wouldn’t be as detailed or precise as in the comic.
