LEGO Ben 10: Alien Force
You don’t need the Omnitrix to access awesome alien forms, just collect all the LEGO Ben 10: Alien Force ($15) figures, and build your own. Big Chill, Humungousaur, and Swampfire all feature glow-in-the-dark eyes and Omnitrix chest symbols. The parts are interchangeable between sets, so get a few and experiment to invent your own alien creations.
