This pet is chosen among three vanity pets as a reward after completing a chain of Children's Week quests that begin in Outland. These quests may be accessed by characters level 60+. See the Guide to Children's Week for a detailed walkthrough of this chain. Other rewards for the final quest include Egbert and Peanut. Collecting all three pets on the same character is possible (over the course of three years) since the quests are repeatable each year. Willy's eye-beam animation activates every 3 minutes. If no critter is in range, the timer resets.

The one thing that always amazes me about minipets is the attention to detail. Case in point: Willy. Here's a pet designed with exquisite features. In fact, if you look carefully at his backside, you'll find that he's even been equipped with the ability to relieve himself. In this way, he's able to wink at you both coming and going! *chuckles*
