Welcome to Backyard Monsters Answers. What would you like to know?

Gorgo is usually good for defending but not great for attacking. A Zafreeti can heal any monster that has any damage, unless it's dead, so if you have a Gorgo, you should also have a Zafreeti at hand. Most Gorgo owners are noobs who everyone likes to attack. So get a Formor because it can fly so most towers can't attack it, discluding Sniper Towers, Tesla Towers and Aerial Defense Towers. Of course, since it flies, it can't be attacked by other monsters except for Terratorns, Rocket Daves, and another Formor. It also can't trigger any booby traps. HOPE THIS HELPS! =]
