Adopt Me is the number one game on Roblox, with 50 million monthly active players and a world record of 1.6 million players online. How have fans reacted to the update announcement?

This is everything that you need to know about it - and what Adopt Me is all about for those who haven’t heard of the online game.

Two of the rarest pets, aside from the Monkey King, were available during a 2019 Halloween event in Roblox Adopt Me! One was the Evil Unicorn, and the other is the Bat Dragon.
