This video took a painfully long time to make so show support. Anyway this might be cringe but.... What can 20k coins get you in Toilet Tower Defense?
Note: This video was edited on capcut and all sounds are from capcut. Anyways enjoy the video and note it might seem little but I spent a lot of time on this.
This is Roblox. (Not sponsored just think its cool to have)
What is Roblox? ROBLOX is an online virtual playground and workshop, where kids of all ages can safely interact, create, have fun, and learn. It’s unique in that practically everything on ROBLOX is designed and constructed by members of the community. ROBLOX is designed for all ages. Each player starts by choosing an avatar and giving it an identity. They can then explore ROBLOX - interacting with others by chatting, playing games, or collaborating on creative projects. Each player is also given their own piece of undeveloped real estate along with a virtual toolbox with which to design and build anything - be it a navigable skyscraper, a working helicopter, a giant pinball machine, a multiplayer “Capture the Flag” game or some other, yet-to-be-dreamed-up creation. There is no cost for this first plot of virtual land. By participating and by building cool stuff, ROBLOX members can earn specialty badges as well as ROBLOX dollars (“Robux”). In turn, they can shop the online catalog to purchase avatar clothing and accessories as well as premium building materials, interactive components, and working mechanisms.

I don't have that much robux right now so I can't really buy luck gamepass, however if I had some robux I would probably buy it.
