How to get to Plexus in Regular (Regular 64) on Roblox 

I really needed help finding this place. But I finally know how by some help people gave me! So I should just show a tutorial where to find it! Because I couldn’t find another video like this.
Story time: I was in a Roblox Regular server right? And almost everyone was in Plexus. I was like, what is Plexus? I try to find out. I think it was underwater but I think I went the wrong way. So I got some help from the Regular 64 Discord server, it kind of helped but not too much. Until someone said “Plexus” in the chat. I had to run because I still think it was underwater. And it was! A little cage in the middle. Just say Plexus and you can go down there! But I needed help to get passed the doors. Shout out to DecayingToe for showing me where is was!
I hope you enjoy/enjoyed this video!
