Making the long trek down from the Astronomy Tower to the Black Lake, you may be a bit surprised to see what looks like a large circular platform floating out about 50 yards into the water. While you can't make out exactly what they are at the moment because of the distance, you are able to see small colorful blobs in each of the four Hogwarts' house's colors. The water, which you may be accustomed to looking calm, appears a bit uneasy and laps up onto the shore with a bit more gusto than usual.

Woah...wait...was that a tentacle just now?!

Professor Flamsteed, with the usual eager grin upon his face, beckons you all to continue following him as he steps into the water and...APPEARS TO BE WALKING ON IT?! Following his lead, you discover this not to be the case but rather there is a slightly submerged platform that allows you to walk out to the floating game arena. Aren't you glad you brought the proper footwear today?

One you have arrived at the floating platform, you discover that the colorful shapes are actually sandcastles scattered about haphazardly around the perimeter with some closer to the edge than others. The water from the lake laps up against the platform and just barely comes over the top of it. Hmmm...how very peculiar...
