I love the look of the Aqua Strider companion pet. I love his glowing blue color and the design on his back!
The pet comes from Hollow Reed which is a rare drop from the Pandarian champion Nalash Verdantis. Nalash can be found in Dread Wastes (approximate coordinates 64,58).
In the picture above the Aqua Strider 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.
