I'm not sure what language this is, but it isn't the same language that appears in my book... Maybe the Trolls speak a different Finnish dialect...

Here's the translation that I was able to come up with, with complete disregard for tenses since I don't know them yet...

Aamund ja Kettil,
(Aamund and Kettil)

koksi työvoima verka
(two men of the cloth)

kylvettää sisällä sauna
(bathe in sauna)

Yllätaäen, peikko voimakas mennä sisään
(Suddenly, trolls forceful enter)

He leikatteet korva Aamund
(They shear ear Aamund)

Ja Päihittää Kettil
(and beat Kettil)

ennen kuin sauna räjähtää
(until sauna explode).

Now granted my tenses, cases, etc., are nonexistent, but the root words would probably be the same. This sounds very different from all the words in the Finntroll song (none of which parsed at finnhun.com)... So I wonder what language that is..
