Be a pony! Explore Maretime Bay! For all the Roblox fans out there, you can now visit the earth pony city. The description promises crystal collecting, soaring with Zipp, a dance game with Pipp, unicycling with Izzy, and much more!
Go check it out over here. I've added the screencaps below too.
Thanks to Las Noticias MLP and Julie for the heads up.
