Nine gross goblins tried out some new fish bait
It attracted piranhas, and then there were eight.

The archive was Saruman's and then there were five.

Five gross goblins wanted to learn some plant lore
One was bored to death, and then there were four.

Four gross goblins met a dwarf named Gimli
One fell to his axe, and then there were three.

The potion poisoned one, and then there were two.

Two gross goblins stared into the sun
One was blinded, and then there was one.

One gross goblin dialed 9-1-1
He was caught, and then there were none.

A/N I don't own any of the characters mentioned except Kevin, but he's really Legolas, so that doesn't really count.
