8.1 PTR - new additions and changes

[Quintessence]

New in today's build (October 3):

Gnomeregan Pet Dungeon vendor (Micro Zoox) updated to include 3 new pets, 1 schematic that teaches engineers how to craft a new pet, and standard Supply Box. All items cost Pristine Gizmo(s).

Gnomeregan Pet Dungeon breadcrumb quest is up. Available from Rachel Kurall (Alliance, outside of Ruff Waters, Dana Pull's store. Not sure about Horde).

6 new pets

• Alarm-O-Dog - Gnomeregan Pet Dungeon vendor
• Leper Rat - Gnomeregan Pet Dungeon vendor
• Mechanical Cockroach - Gnomeregan Pet Dungeon vendor
• Mechantula - Engineering
• Mini Spider Tank - Achievement reward
• Wicker Wraith - Achievement reward

New "Family" style achievements for BFA - "Family Battler"

--------------

At least 5 6 new pets so far:

• Enchanted Tiki Mask (finally added a recipe for this pet)
• Child of Pa'ku
• Feathers
• Redridge Tarantula
• Spawn of Krag'wa
• Thunder Lizard Runt

New increase to the Pet Journal: Interdimensional Pet Portal

• Increases max number of total pets in your journal to 2k. Costs 1k Polished Pet Charms. It's unknown if it will require already having the 1.5k increase, or if there are any other prerequisite.

Child of Pa'ku - Raid
Feathers - A Quest
Redridge Tarantula - Venomarus - Arathi Highlands (looks like a copy/paste job of Fuzzy Creepling)
Spawn of Krag'wa - Raid
Thunder Lizard Runt - Raid

There is a gnome outside Gnomeregan dungeon portal called Micro Zoox (he offers a BFA engineering pattern - Mechantula - a champion equipment - not a pet) and Unopened Gnomeregan Supply Box (text is usually contains pet supplies and some pet charms)
So he is likely the pet dungeon starter npc and the box will be the reward but contents haven't been updated.

The supply box is free at the moment and is giving shiny pet charms and 1 level family stones plus the usual treats, size changing items, bandages. Didn't see anything interesting in 20 boxes.

Newest build adds a Familiar Familiar-style achievement for BFA, Family Battler. Awards the Wicker Wraith, currently.

There are a few new pets as well. In addition to the Wicker Wraith, there is the Mini Spider Tank, which is the reward for completing the Gnomer pet dungeon.

There is also:

•Alarm-O-Dog
•Leper Rat
•Mechanical Cockroach
•Mechantula

I assume the first 3 are vendor rewards for doing the dungeon multiple times (like the Pocket Cannon for Deadmines). Previously, the last was associated with an engineering schematic on that vendor.
