Forgot to answer the questions!
1. Because of the colorful "Blue" trees and grass, it looks nice and chilling to me, even though, I'm not a fan of blue.
2. The first thing I do is probably say "Yay!" In real life, then go ahead cut trees in the Warped Forest, then I go back to my Overworld base.
3. Probably I'll be like: "bruh why am i here bro" then I'll try to go to another biome.
4. The almighty V I L L A G E. (insert epic jotaro theme here)
Thanks for making these questions, I've had so much fun answering them, Also, my favorite Overworld biome is an Ocean Island, reminds me of holidays!
