We need reinforcements!

The Professor has taken to thinking of our balloons as soldiers guarding the seed from the unseen enemy. If that is the case, these soldiers need some R&R quick! Some have popped and most are wounded (deflated), but they are still standing guard and we haven't seen a bird yet except the ones sitting on the fence scowling at our colorful troops and tilting their heads as if to say, "I shall return!"

I think we are going to try one round of reinforcements; maybe a different kind of balloon will be sturdier. If those don't hold up any better, we might try some strips of mylar.
