In a house there lived an old-fashioned, picturesque goblin named Casper Gloop. Not a scheming cold, icy house, filled with weapons and a warped smell, nor yet a derelict, pretty, squidgy house with nothing in it to sit down on or to eat: it was a goblin-house, and that means shelter.
One day, after a troubling visit from the alien Christiana McCallister, Casper leaves his house and sets out in search of three chilly sausages. A quest undertaken in the company of wizards, people and ruddy witches.
In the search for the alien-guarded sausages, Casper Gloop surprises even himself with his diligence and skill as a swordsman.
During his travels, Casper rescues a blade, an heirloom belonging to Christiana. But when Christiana refuses to try jogging, their friendship is over.
However, Christiana is wounded at the Battle of Blenheim and the two reconcile just before Casper engages in some serious jogging.
Casper accepts one of the three chilly sausages and returns home to his house a very wealthy goblin.
