Inscrutable... ?

It would be wrong to say that the Frog doesn't have a range of facial expressions - he has several.  It's just that mostly they're quite visceral.  And by that, I DO mean linked to his digestion: either unimpressed with input strategies, or disturbed by the output processes. And of course he has his blinding smiles.

But for the rest of the time, he's really a fairly earnest little soul, not given to wearing his emotions on his sleeve.  Or so I thought.  In fact, if you know how to read the Frog, it's all fairly easy.
