Purchase a Foam Sword Rack from Craggle Wobbletop and then return your ward to the Stormwind orphanage by speaking to Orphan Matron Nightingale in the Cathedral District.
You have been so very kind to me, <name>. I never dreamed that I'd have so much fun during Children's Week. Thank you.
I wish all the orphans were lucky enough to get to do the stuff we did. Do you think we could find Craggle Wobbletop again and get a foam sword rack from him? I think he's still pushing that cart in the Canals outside the Trade District. That way, everyone else at the orphanage could do something fun too!
After that, it'll be time for me to go home.
