World Event: Primal Bear Cub
Zone: Azure Span

Earn and equip the Honorary Dryad title from a short quest chain in Valdrakken, and gather up 3 Hornswog Hunks and 1 Honey Snack. Then head over to The Azure Span to find the Primal Bear Cub (located between the Theron's Watch flightpath and Rhonin's Shield flightpath). Interact with it to receive this pet.

Primal Bear Cub: The location for NPC is /way #2024 67.6 18.6 Primal Bear Cub

Honorary Dryad Title: You can receive this from Thalendra in Valdrakken, located at /way #2112 72.8 66.0 Thalendra
You can receive the title from a short quest chain, and after that point she will offer a weekly quest to obtain the title again.
This is a temporary title, and will easily drop from your character. If you're looking to get the Snowclaw Cub, have all your food items ready before getting the title, then fly directly to the Primal Bear Cub's location indicated above.

Honey Snack: Before the Forbidden Reach unlocked, players could only obtain this food item from the Worldbreaker's Vendor in the Waking Shores.
Now all you need to do is fly to the Forbidden Reach and purchase a stack from Kraxxus in Morqut Village not far from the flightpath at /way #2151 34.0 59.8 Kraxxus

Hornswog Hunk: This can be farmed from Hornswogs, or purchased on the Auction House.
