Pet Plethora. Mr. Grubbs.

In Eastern Plaguelands there is an NPC Fiona [9,66]. She has 2 Quests That you are going to have to do. Once you do the both of them they will lead you to her again they are a total of about 6 quests. You will have to do them until the carriage has a blue question mark. When this happens you will get to choose the buff "Fiona's Lucky Charm", blue rabbit's foot icon. I Continued on the quest line so that I could work toward's the Achivement of doing Fiona's whole chain. After getting her to the second tower I had looted enough  Hidden Stash items from mobs. 


When you open enough of them you will have Mr. Grubbs. The Hidden stash and the Mr Grubbs are both BOP so dont bother trying to farm more of the bags for pets but at 85 I found it was easy enough to do the quests and keep getting extra few silver to do the zone questing and working on more achivements. Due to the buff timer lacking I belive that you can continue to get a bit of bonus as you keep the buff up.
