Who is the most insidious monster from Rainbow Friends! Of course, Purple! He doesn’t attack openly. You can’t see him because he is lying in ambush. But if you come by, he will try to grab and kill you. The main thing you need to know about Purple is that he sticks to the ventilation system and likes attacking out of the water. So you have to be careful and avoid coming up close to any sources of water on the map! Can you survive?
