The Children’s Week brings about two new companion pets as reward by completing the world event quests. In Orgrimmar and Stormwind, go to the orphanage. Talk to the Orphan Matron to initiate the questline.
At the end, you will be able to pick one out of three rewards. The new pet Scooter the Snail is a reward for completing the Orgrimmar Children’s Week quests.
You can get the new pet Legs from completing the Outland Children’s Week quests. You can start these by talking with the Orphan Matron in Lower City, Shattrath. South of the World’s End Tavern.
Better hurry up. Children’s Week ends on Sunday, May 8th at 3:00am.
If you ever missed buying the Blue Clockwork Rocket Bot from Jepeto in Dalaran, you can buy it from Blax Bottlerocket, an NPC vendor that roams the Drag in Orgrimmar, or from Craggle Wobbletop in Stormwind.
