Easy basis of this song. Jareth (the goblin king) is trying to figure out what kind of goblin to turn Toby into. If you find this confusing lets scroll back. All of the goblins that Jareth has are children that were wished away from their home as Sarah did with Toby. Either the people didn't have enough time to save them, they didn't care, or they could restate the strong line of "you have no power over me." Jareth is felling as if Sarah wasnt going to make it in time to save her little brother so he starts thinking what kind of goblin should this baby be?
