Notes

Patch 3.1.0 (14-Apr-2009): Engineers can now obtain the schematics for Lil' Smoky and the Pet Bombling from certain creatures found in Gnomeregan. Specialized Gnomish or Goblin engineers can obtain both schematics equally. The repeatable quest that used to randomly grant these schematics has been disabled.
