I was a little disappointed with the Giant Bone spider.
I really wish she would of look more like the boss you get her from (I included her picture at the bottom of the post). Now she is one pretty spider!
The pet comes from Dusty Clutch of Eggs which drops from the boss Maexxna in the raid Naxxramas.
She is part of the achievement Raiding with Leashes.
In the picture above, the Giant Bone Spider is under the effects of Papa Hummel’s Old-Fashioned Pet Biscuit. The biscuit doubles a targeted Non-Combat Pet’s size for as long as it remains at its master’s side. The biscuits are a common loot card from the trading cards. You receive a stack of 50 biscuits when you redeem the code and you can stack up to 250 biscuits. Get biscuits for your pets.
