Upon reflection, compressed helium might not be an essential ingredient for making light, yet filling, cookies after all. I never claimed to be much of a baker, but they say you learn by making mistakes; sorry about that Blue!
It sure seems a waste to just throw these cookies away though, anybody want one? I don't hear any complaints about the taste. Just save some for Blue when he gets back down, they're a treat for him after all.
Blue is Blue.
