Description

[ * Welcome, little one. This is the underground. ] Hey there! Welcome to UNDERBLOX: A Roblox UNDERTALE Fangroup! Chat about undertale, AU’S, even play games together! We have some t-shirts for sale, more will come. And maybe we’ll put some effort in and make shirts and pants. Rules: 1. Don’t be rude! We all love joking around, but try not to argue! 2. Be kind. We’re all friends here! 3. If you have group perms, don’t change things without Charas (the group creator/owners) permission! 4. Use your head and have common sense. Thats it. Thats all for now! Rules may be changed or added. Enjoy your stay!

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
