Gekkies Greed Quest Guide

To start this quest you need all of the HealthPedias (just so you know, they include: bear, bird, bovine, cat, dog, elephant, mustelidae, primates, rabbit, wild canine and wild cats) in your bookcase and you must have read them.
Gekkie usually asks for weapons that really range in price from cheap to expensive, and information from the HealthPedias.
He gives out sticky puzzle pieces (there are 12 in total).
