Hey FvLegends! In Stage 2 of the FarmVille Roaming Dinosaur pen you can “catch” a free Irritator Dinosaur when you entice it to stay on your FarmVille farm by completing a few required tasks. Hurry though, as you’ll have to gather the required materials within a special time frame of 4 days, 23 hours.
Remember, if you are having trouble locating this feature, just check on the outskirts of your FarmVille farm, where lost, lonely, and roaming adoptable animals usually appear. You can also click on the in-game Dinosaur icon located on the right side of your FarmVille game play area.
