(I'm honestly not sure where to put this, so if an admin sees this is wrongly placed, feel free to move it to a better place)
My game just updated on Steam and I went to the tutorial level to test out the squad mechanic (which is great), but I noticed that middle dummy has a red helmet (edit: and a yellow bandanna) on that I've never seen before.

After several refreshes, i've seen Kanye shades, fireman hats, bandannas, top hats, sunglasses. Anyone seen any other goofy hats? I assume this has to do with a holiday that recently came upon us on the first.
