Because I would not be writing a new story about Tinkerbell, I would be trying to convey the idea that Hydrogen is "tiny and hot tempered", just like Tinkerbell, while Helium is "quite small, but not as tiny as Hydrogen, and very peaceful and self reliant"... just like Master Yoda. Of course I could use GenericFairy#274, or MidgetZenMaster (my appologies to any Little People reading this, but I am not going to risk to use the word Dwarf and jump from Disney's frying pan into Tolkien's firestove), but that kind of defies to purpose of using visual imagery the kids already are familiar with. Call me a sore looser, but I am not particularly happy with Disney having called dibs on the human herritage of the last 3,000 years and claim it was their own purpose. The only original work from old Walt was their horrible looking antropomorphic animals, everything else was taken from the public domain, repackaged, and ear marked as their own.
