That red Pacman-looking creature with gnarly teeth is the Angry Critter, it's based on character/s that appear in their short film, Arcade Trap. Besides this Angry Critter papercraft there's also a Happy Critter model and lots of 2D grass elements.
Next is the Piccolo papercraft and his watering can, this character is from their award-winning short film, Sam and Piccolo - haven't seen the film, but definitely planning to see it when I get some free time from work.
You can also download a Bolex camera papercraft, based on the very popular Swiss made 16mm non-sync camera.
So there you go, free papercrafts, don't forget to browse around their site and check out some of the other cool stuff they've got.
