Making bubbles.

is that a camel or llama? I've read that they bubble just before they spit!

lol. Fran, this was camel born with the silver spoon in his mouth/American chewing gum, as he did not spit at all.

I think they only do it when they get annoyed - lol and I read that they're born bad-tempered!

Well, I can tell you, their nose architecture/architecture of the nose, is a real miracle. Ten years ago I did one research, during which I learned from other scientist, that camel´s nose is an extraordinary water saver.

and I beleive that they can close their notstils to keep sand out during storms! though not sure how they breathe, then, though ...

LOL. Fran! :)))
They are miracles of the nature, that´s for sure.
