So the song starts off a little weird:
You and I in a little toy shopYou'd think they'd need to be helium filled balloons. The "money we've got" line makes it sound like they don't have much, and they don't mention anything about purchasing a helium tank... perhaps it's a super windy day or something? Maybe the balloons were prefilled with helium? (Though would 99 of them fit in a bag?) Or maybe it's something much, much more sinister...
Buy a bag of balloons with the money we've got.
Set them free at the break of dawn
'Til one by one, they were gone.
Take a look at the ending:
It's all over and I'm standing pretty.
In this dust that was a city.
If I could find a souvenir.
Just to prove the world was here.
And here is a red balloon
I think of you and let it go.

It's been a while since I've seen that film, but maybe Le Ballon rouge was just a scout... in fact, possibly that young boy should be tried as a collaborator!
I, for one, welcome our new floating latex overlords.
