One of the building that will be available to players once we arrived in FarmVille’s Haunted Hollow is the Monster Lab. It’s a breeding building where we place up to 20 Monsters inside the Monster Lab. Once you harvest the Monster Lab it will give “Serum” on which you can use to create more Monster by exchanging these serums. The more monster the Monster Lab has the more chances it gives rare color “Serums”. You can have multiple built Monster lab. All exchange Monster can be found in the Gift Box.

Tips on how to get the serum you want:
If you’re aiming to get a specific color of serum for example a “Green Serum” the best way to get it is to remove all the monster in your Monster Lab and just place the monsters that gives “Green Serum” on this case the Frankensheep or the Cow Horse.
If you’re aiming to get “Orange Serum” then just place only the monster that gives “Orange Serum” like the Mummy Duck or Giant Moth. Don’t mix it with other monster like monster that gives “Blue Serum” or “Green Serum”.
