[MF] I suspect it's CENTESIMO being the Uraguayan sub-currency. I except you'll be able to work out how to get there from the clue, so I shan't insult you by explaining it. Look forward to sitting down with a crossword later...

There's an "EN" I can't account for.

Took me a while to re-work out the logic: it comes from the fact that Paul's = MINE.

How about Scale back creature (6)

Only thing I can think of is animal, not a common usage of "scale" though.

Nice to see you back [Blob]. This game's lost a bit of momentum, what with you being temporarily frozen out - and rab peregrinating all over the place. Anyway, I left a clue a while back - which doesn't appear to have been solved. I think it's disappeared off the top.

[rab] Great word, eh? One could imagine Kenneth Williams squeezing every last sinewy syllable out of it - much like the way he uttered his favourite word 'proclivities'.
