8.1.5 PTR: New Pets From Raiding With Leashes VI, Children's Week, DMF

DMF balloon companions cannot battle and are not cageable.
We're kicking off 2019 with a new PTR cycle. Patch 8.1.5 PTR is up and new Pet Battle content was added.

At least 20 new pets so far:

• Raiding with Leashes VI: Pets of Pandaria (Mogu'shan Vaults, Terrace of Endless Spring, and Heart of Fear)

- 11 dropped pets and 1 meta-achievement reward

• Children's Week updates

- 4 new pets

• Darkmoon Faire additions

- 3 new pets

• Last but not least, 1 pet from "A Quest"

Some of my personal favorites/highlights of the RWL6 set.
Full list of 8.1.5 datamined pets can be found here.

The Pet Journal doesn't list specific bosses for the RWLVI pets yet. It's interesting that there are only 3 MoP raids listed for the achievement too. The last raids, Throne of Thunder and Siege of Ogrimmar are missing from this set of RWL pets. Will these 2 raids get their own RWL treatment? Or will they simply not be included? There are a number of pets that already drop from these raids, but we'll have to wait and see if they'll be grandfathered into RWL or if they'll stay as separate, standalone drops. Whatever Blizzard decides it may set precedence for future similar situations where pets are released as drops from raid bosses ahead of that particular raid's corresponding RWL achievement.

List of existing MoP-raid dropped pets (Throne of Thunder & Siege of Orgimmar):

• Blackfuse Bombling
• Droplet of Y'Shaarj
• Gooey Sha-ling
• Ji-Kun Hatchling
• Kovok
• Living Fluid
• Living Sandling
• Pygmy Direhorn
• Son of Animus
• Viscous Horror

The Brawler's Guild will also be making its return. No new pets from there so far, but the 2 previously released pets (Clock'em and Tylarr Gronnden) will be available again. Same requirements as before.

That's it for now. They only announced the return of the Brawler's Guild and Children's Week updates during last year's BlizzCon preview of 8.1.5, but it's possible more Pet Battle content (even more than RWL6?!) could be added in this upcoming patch. We'll have to wait and see.
