All correct,
Kath. Well done - particularly for guessing
The Perky Ent.
Now, how about the remaining ones ...?
Btw, it occured to me on composing those that, if
Sophia the Thunder Mistress were to marry
Son of Numenor, they could call their son
Thunderclap Numenor - and
SoN could proudly declare that there was
Something in the Heir.

Edit: Correct too,
Shelob.

And that, if I am not mistaken, is
The Perky Ent's translated name using the Japanese/Chinese/Korean function. Kind of fitting for an Ent, don't you think?
