Cardano Logo — Well, this one is tricky to miss, for it the one being rewarded to you for walking through the Cardano logo in the entrance hall
Flying Stingrays — Watch the video while standing still, no chatting, no looking around. just stand there in front of the main stage. I did it 3rd person AFK.
Friendly Sprites — Simply walk towards or jump around jellyfishes and butterflies
Gentle turtle — You need to keep on chatting in text
Magical Bison — Walk into every pond in the main area. Do not miss a small pool (you got it? eh?) next to "adoption" teleport
Tree of Life — You need to participate in the voice chat with a few people. You can be silent, but I kept my mic unmuted
Beautiful Butterflies — Get to every single island on the summit. Just so. I did that using teleports, but maybe it will work out of the menu
