Contraband Birthday Bash
Note: This is also one that doesn't have a specific place, other than the short period where Tonks' auror class was on Avalon, and she and Horace explored the island when they weren't supposed to.
"Well, that certainly wasn't the best idea they ever had," Lockhart giggled as Horace Smeltings got the frosting and cake cleaned off of his face.
Tonks, in one of her solo adventures over Avalon, had made friends with a wizard in section two who had been to Diagon Alley to help in the cleanup after the battle.
Apparently, this wizard, thinking that everyone could use some cheering up after the messes at the ministry and at the Alley, had "contributed in the rebuilding effort" by purchasing all he could afford of what remained of Gambol and Japes' stock, including some exploding birthday candles.
Tonks had managed to wheedle Horace's birthdate out of him, and had teamed up with the wizard from section two to throw an illicit birthday bash.
Poor Horace never knew what hit him—but it sure was tasty.
