Thanks, kat and Charley. ;-)

Kat, let me know if the young fella likes it, even if he did mean crocodiles. Grownups! They never get anything exactly right!

My younger sister, when four or so, had a great talent for re-working words. We still often refer to helicopters and pussycats as pollypoppers and tuppa-tas. She's in her middle forties and is long resigned to this mildly humiliating family teasing.
