If you enjoyed farming for the
Disgusting Oozeling then you are going to absolutely LOVE the Cataclysm pet
Mr. Grubbs. However, there is a slight difference between farming for the oozeling and Mr. Grubbs.
Before you can even go out and start killing a bunch of mobs in hopes for a special loot bag, you will need to do some prerequisite quests to gain a buff that will allow you to see the bag on the creatures.
The quest chain starts in Eastern Plaguelands, from the NPC
Fiona. She stands just on the side of the road at the
entrance of EPL from Western Plaguelands. Cross the bridge and you'll see her with her horses and carriage.
She will then send you on two quests to find her companions. Each one will then have you go on two more quests (one for each NPC) before having you return to Fiona. After completing all the tasks requested of you, she will give you a quest to "hop into her carriage."
You do NOT have to accept or complete this quest in order to receive the buff necessary to farm for Mr. Grubbs.
Fiona's carriage should have a blue question mark above it and upon clicking on her carriage, it will offer three buffs. Choose "
Fiona's Lucky Charm" and it should give you a buff with a blue rabbit's foot icon. This buff has no timer and will persist so long as you are in EPL. It will disappear if you leave the zone, but will reappear if you return.
Once you have that buff, you are good to go kill yourself some grubs, devourers or any type of mob within EPL!
Should you choose to farm strictly from grubs and devourers, these gigantic yellow worm are actually quest mobs and therefore don't really drop anything of significance if you're not on the quest. Having a low level character join your party to loot the quest items while a higher level toon annihilates everything is a strategy that may cut down on farming time. If the lowbie doesn't also have the Lucky Charm buff, they won't be able to see or loot the bag. Since the loot bag (called
Hidden Stash) is not a 100% guaranteed drop, having someone else loot the mobs will help you see which ones have a loot bag on it for you to collect. This means wasting less time bending over to check each body for a bag. (Yay for efficiency!)
Anyway, this is where the mechanics of farming for the Disgusting Oozeling come into play. The bag itself has a low drop rate, nevermind the chance of the pet actually being IN the bag that you've looted. Most bags contained a few copper to a few silver. The number of mobs you have to kill may vary, but be prepared to kill A LOT of mobs.
Some last notes - the mobs that drop the bag are level 40 to 42. The hidden stash is bind on pick up. Mr. Grubbs is also bind on pick up (unlike the Disgusting Oozeling).
True to
this video, Mr. Grubbs will randomly do back flips up and over your head!!
