Use Zorbin's Ultra-Shrinker to zap any kind of giant found in Feralas into a more manageable form. Bring 10 Miniaturization Residues found on the zapped versions of these giants to Zorbin Fandazzle at the docks of the Forgotten Coast, Feralas.
I know you've gathered residue for me already... but should you find yourself for want of an encore performance to a fun-time activity, I can always use more residue.
While I can't offer nearly as much in the way of compensation again, I'll be more than happy to spread the good word of your service to all my goblin friends with ears.
Believe me $g sir : madam; when I say that these goblins have quite large ears.
