Underground Pool

Where is the Underground Pool?
In the Town, there's a manhole that has a ladder partially coming out of it. When you go down this ladder, you can access this cool pool. When jumping in the water of the pool, there's an invisible block that prevents you from reaching the bottom of the pool. It simulates swimming.

Unused Water Party Skit
This pool was an important part of the unused Water Party Skit which was not uploaded on the Roblox Chat Youtube Channel. One of the windows was broken during the skit, and the three protagonists make a water party because of it. The actors were SamirTheGamer4, Executivity, and Eviled123123123.

Alpha Party Info
Fun fact: the Underground Pool was closed during the Alpha Party and before that. There used to be no water, just an empty pool you could fall through. Also, you could jump through the windows. The manhole was covered with wood during this point in time.
