Then I noticed that the poor fellow's arm seemed to be stretching. Can frogs stretch their arms out like that? Suddenly the 'arm' was way too long to be an arm - and the truth was very clear. The frog was being eaten by a snake! The snake was gripping the frogs neck and the frog was struggling to get free! That explained the squeaking. (I've lived here long enough to know that snakes squeak.) Poor frog!
I called Victor over and he immediately began throwing clumps of soil at them to try to free the frog. (Victor hates snakes. And is rather fond of frogs.) He succeeded, the snake recoiled, the frog fell... we don't know whether to his death or to freedom. You can imagine whichever ending you prefer.
Only in Thailand, hey?
