What a Long, Strange Trip Back Home

I really like all of the new holiday hearthstones, but this one is my favorite so far. I can't tell if it does something different on each use, but my Tauren blew a kiss at the end and my Goblin doesn't seem to do that. I love the fireworks on this one, though, and the Lunar Festival hearthstone, and I can't wait to see the rest of the holiday hearthstones for the year.
My brother asked if there was going to be a meta achievement for collecting each holiday hearthstone, and although there doesn't seem to be anything right now, I think they ought to make one. The Children's Festival hearthstone should require PvP, too, just to make the whole thing feel like a challenge. :D
Or maybe not.
I still think it would be a fun reminder of the reason I did all of the holiday achievements in the first place; a nostalgic nod to the achievement that actually made me feel like I'd achieved something.
