Late for Birthday

How to get the skin:
Teleport to the Safe Place map.

Go to the green floor (You'll know which one it is because there are green squares on the wall of that floor)

Go inside, and the walls and furniture should be green. You can now verify that this floor is the green floor.

Go to the end of the hallway, where you'll see two rooms. Go into the room on the left, not the right.

You should see a few washing machines and a pile of clothes on a table. Go to the very end of the room, where there are two washing machines next to a corner.

In that corner, you should see a birthday hat. Stand on/touch it and you'll get the Late For Birthday badge.

After touching the birthday hat you will get the Birthday Piggy badge.
