Prepare to venture down the rabbit hole!

Everything looks so surreal: Mushrooms are left and right, Planes of Hearts are in the skies, and passengers have started seeing unusual egg-shaped buildings around! It's not madness, it means Wonderland has come to your city and you can travel to it in a new event: take down those mushrooms, send your fleet to event buildings and even Wonderland itself, and gather some unusual collections! Will you be able to collect all Egg buildings?
