Theres another delivery but the person delivering it is a bird. This could be steves issues presenting themselves once again, but he doesn't say anything.
it's just another surprise, intertwined with something familiar (the mail). the surprise is that there is mail on the top of the mountain, and how did it come so quickly, how did anyone know steve was up there, etc etc etc. and it's a bird because why not. also i have no idea what kind of bird that is. some people said it was a kiwi but i just made something up. the script said it was actually supposed to be a penguin, but i was working off phone timers to get this thing done (video making takes a long time, you gotta stay on top of the time) so i just drew the fastest thing i could. turned out to probably not be a penguin.
