I used Bloodgazer Hatchling (1, 1, 1) Legs (1,1,1) and Ghostly Skull (1,1,1). All are fairly simple pets to get: the Hatchling can be found during the Bloodgazer Swarm World Quest, Legs is a Children's Week award, and the Skull can be bought in Old Dalaran, in the Underbelly. Darahir's the vendor; choose to track Reagents from the minimap to find him easily.
