Tranquil Mechanical Yeti Unlearnable Or Learnable?

Simply Abominable

Mechanical Yeti Pattern Is Obsolete

Tranquil Mechanical Yeti is no longer available to engineers that haven't already learned it prior to Cataclysm.  The recipe was formerly learned from completing a quest chain in Everlook, Winterspring.  Any engineer that completed the quest chain would be automatically rewarded with the ability to craft the Tranquil Mechanical Yeti vanity pet.  This is simply not possible anymore and has been confirmed via an in-game GM.

EDIT:  Apparently BLIZZ has GMs verifying incorrect information as the recipe is still learnable.  See the comments below for how to learn it.  I apologize for the mis-informed post.  We all make mistakes and this is my first one on the blog.  Thanks for the comments and corrective responses.  Again, I apologize.

Older Engineers Rejoice

This is good news for engineers that already have the ability to craft the Yeti vanity pet.  Any new engineers will be unable to learn this, which creates a great item to sell for the older engineers.  This limits the number of competitors able to craft these, which makes the Tranquil Mechanical Yeti an excellent item to sell on the auction house.  

Engineering Craftable Vanity Pets List 

The current roster of craftable engineering vanity pets is:

1. Mechanical Squirrel Box
2. Tranquil Mechanical Yeti (Pre-Cataclysm Learnable Only)
3. Lil' Smokey
4. Pet Bombling
5. Lifelike Mechanical Toad
6. Personal World Destroyer (Goblin Engineering Only)
7. De-Weaponized Mechanical Companion (Gnomish Engineering Only)

Hope you weren't slacking in your ability to learn and craft the Tranquil Mechanical Yeti.
