What do we have here?
Fiber one is utilizing one of the archetypes to sell deliciously healthy Fiber One Chewy Bars. The terrible 'Mamagus' Alien has captured an Astronaut and won't release him until he eats a snack!! The terror!!!!! The Alien in the case only appears irrational to the Astronaut (WHY?! WHY MUST I SNACK!?!). Only when the kid tastes the snack and sees for himself that it's tasty does the Alien disappear and revert to being a normal human being (aka Mom). The Astronaut, however, stays in character.
Coincidence? Perhaps. But snack buyers everywhere will note the Astronaut's new discovery.
