So this is a really cool thing that Club Penguin has done for the first time and I hope that they will be doing more of these. You have to face 3 challenges and you can get free items on the way.
Challenage 1: Light all the orbs ( step on blocks in front of orbs)
Challenage 2: Hit targets ( throw snowballs at targets 50 times, thankfullay there is a counter)
Challenage 3: Maze ( follow these directions to get final free item: Down, Left, Down, Right, Right, Up.)
So if you when you complete all the challenages you should have golden sheild, golden helmet, and golden amour.
