"Tommy Three-Buttons, are you ready to show off your pet?" Ms. Haberdash asked in her shrill voice. She looked askance for a moment. "This isn't about your once-an-hour trick, is it? Because that's many months off yet."
"No, ma'am!" Tommy answered. "This is about my best friend! It's my Willy!"
"Hmph," Ms. Haberdash said. "Isn't it always? Okay, proceed, Tommy."
"Everyone, I'd like you to meet Sleepy Willy!" Tommy said as he took the podium. The little creature hovered a few inches off the floor next to him. "He has one eye! And when we go into dungeons, he floats around behind me. And if the tank isn't pulling fast enough, Willy totally falls asleep, and it's very cute, and the girls say 'Awwww.' They really like my Wil ... "
"Tommy!" Ms. Haberdash interrupted. "Please, keep it clean and stick to the point."
"He also shoots a laser beam from his eye and kills critters!" Tommy said. "He's the best one-eyed Will ..."
"How did you meet your pet?" Ms. Haberdash interrupted again.
"It was for Children's Week," Tommy said. "There are these totally unlucky orphans in this place called Shattrath. Shattrath's been abandoned for years, except as a thoroughfare for those weird death knights. I guess it's like their clubhouse now. But, the orphan matron -- she's old like you, Ms. Haberdash! -- gives you a pet for helping the orphans out for a little while. There's even a Dalaran matron, but she doesn't have a cool Willy like me!"
"I think that's enough for now, Tommy. Please, take your seat by bubble-hearth. Thank you for your presentation."
Name: Sleepy Willy
How to get it: Complete your Shattrath quest for Children's Week
How to get rid of it: It's a pet. It takes up no inventory. It just kind of sits in your spellbook. But if you don't take it out and use it, it's going to rust.
