Day 4's door flap is really wide, which must mean we're getting something really cool, huh? Let's rip it open and... it's slime. A bag of slime. A bag of bright, neon green slime. I never even played with slime when I was a kid, I don't care about it now. This is a wasted day.
Oh wait, I didn't open the flap far enough, there's another thing in there. So we get a bag of slime and also a... curled-up Gremlin? A Gremlin egg [cocoon --ed]? Whatever it is, it would probably look pretty cool covered in slime. Too bad that's not my idea of fun.
