Guardians of the Galaxy (film)/Fridge

Fridge Logic

 * Groot disintegrated into thousands of twig-sized bits. Why would the one that Rocket picked up be the only one that could take root and grow?  How do we know that there aren't dozens more Grootlings growing on Xandar?
 * Many of the non-humans on Xandar have skin in the shade of one of the four pigments used in the four-color printing process used to produce comic books -- most notably bright magenta and an intense chrome yellow. This was a not-uncommon shortcut when coloring aliens in comic books.
