Eat Dirt Cheap/Playing With

Basic Trope: A character or species eats earthen materials for most of their diet.
 * Straight: Larry eats mostly dirt.
 * Exaggerated: Larry is completely unable to digest anything besides dirt, rocks, and the like.
 * Justified:
 * Larry is part of a species with very basic nutritional needs; all of their nutrients can be found in dirt, so they eat that, which is far easier to come across.
 * His nutritional needs are very mineral-heavy; not all of the necessary minerals can be found in organic matter, and he requires none of the vitamins present in it.
 * Inverted: Larry is completely unable to eat anything earthen, even if it's just a speck or two of dirt in his salad.
 * Subverted: Larry eagerly digs in to a plate of dirt, rocks, and gems, but spits it all out right away.
 * Double Subverted: Because the dirt, rocks and gems were all the wrong kind.
 * Parodied: When a rockslide comes between Larry and his party, he hungrily pulls out a knife and fork.
 * Deconstructed: Larry eats dirt, but because he is delusional and thinks it's real food.
 * Reconstructed: It wasn't really dirt; it was crushed up cookies and chocolate chips for a prank.
 * Zig Zagged: Larry sometimes eats dirt and sometimes eats plants and meat.
 * Averted: Larry has a normal diet.
 * Enforced: "The rock guy! Make him eat rocks!"
 * Lampshaded:
 * "Is it normal for a guy to guzzle down dirt like that?"
 * "I have never heard a crunch like that before, and I hope to God I never hear one like it again..."
 * Invoked: ???
 * Defied: "No, I do not eat rocks! Why do you humans always jump to conclusions about the stone people?"
 * Discussed: "Mmm, these rocks are DELICIOUS! Igneous, if I may ask? Best kind."
 * Conversed: "Did that guy just...eat a rock?!"
