Trapdoor.

Opening lyrics.

Somewhere in the dark and nasty regions - where nobody goes, stands an ancient castle. Deep within this dank and uninviting place, lives Berk - "Hello" - The overworked servant of the thing, upstairs - "Berk! Feed me!". But that's nothing compared to the horrors that lurk, beneath the trapdoor. For there is always something down there, in the dark, waiting to come out...

Don't you open that trap door,
Your a fool if you dare,
Stay away from that trap door,
Cos' there's somethin' down there.

Closing lyrics.

Creepy, crawly, slimy things that stick onto your skin,
Horrid things with tentacles that want to pull you in,
Squirmy, worms, slugs and snails that lie there in a goo,
They'll wait down there forever till they get their hands on you.

Stay away from that trap door,
Cos' there's somethin' down there.
