PH has left, and now Rookie has come to take her place at the April Fool’s Day Party! There are 4 free items, as well as a member catalog located in several of the box dimension rooms on the left side (The side with the Stair Room, but the catalog isn’t in the Stair Room).
Free Item 1-Blue Propeller Cap, Plaza or Town:
Free Item 2 and 3-Box costume and Box Shoes, Box Dimension (Center Portal):
Free Item 4-Box Hat, Cream Soda Dimension (Right Side, 3rd from top):
If you need help getting through that dimension, here’s how I did it. Start at the center barrel on the starting island, then keep going back into whatever box you come out of.
