How far can I go?

I go to the plaza every day to get the diamonds from the 'Suspicious Treasure Chest', but I always get caught in a huge crowd when the chest recharges, and I lose track of where I am 😅 So, I tried to avoid the crowd and see how far I could go by sticking to the edges, and surprisingly, I was able to go all the way into the sea. Maybe my mushroom dragon is enjoying a swim too?
