I doubt that there will be many people reading this blog, but if you have please post a comment.
Poptropica Mythology island is now out to members and since I am a member, I have been on, and it's really fun! I still think Astro knights is the hardest, but probably 24 carrot is still my favorite. I love Dr Hare, and there used to be a cheat where you could look like him, but I've tried and it doesn't work anymore.
One cool cheat you can do on Poptropica is to press Ctrl shift and then 'S', and you can change your skin color. Also if you press Ctrl shift and then 'R', you can change your clothes mouth hair, skin color, accessories, and what ever you're holding in your hand. Ctrl shift and then 'H', changes only your hair color, and  finally, Ctrl shift and then 'P', lets you wear a pumpkin on your head. Cool eh?
