Impossible Item Drop/Playing With

Basic Trope: Monsters, when killed, drop items that they couldn't possibly have been carrying.
 * Straight: Adele the Adventurer kills a pixie and gets a suit of plate armor.
 * Exaggerated: Adele kills a poisonous mushroom spore and gets a Humongous Mecha.
 * Downplayed: Adele kills an enemy soldier and gets cool flaming magic sword but when the soldier fought Adele a minute ago there had been no flames.
 * Justified: ???
 * Inverted: Alice kills an enemy soldier and gets everything he would have been carrying in real life, including the underwear.
 * Subverted: Adele kills a pixie and gets a message about a suit of plate armor, but it is pixie sized.
 * Double Subverted: ...But the pixie's other drop is a morning star sized for giants.
 * Parodied: Adele has to cross a swamp and because of all the flies she soon has more powerful magic items she can carry.
 * Zig Zagged: Item drops either make or do not make sense, depending on the mood of the Random Number God.
 * Averted: There are no item drops.
 * Enforced: "It'd be a lot of work to give specific drops to every monster type, and our game isn't that realistic in the first place."
 * Lampshaded: "Wow, I wonder where that pixie kept that armor."
 * Invoked: ???
 * Exploited: Adele is imprisoned in a dungeon without equipment, and so she kills rats, knowing that after five or so she'll have enough stuff to beat the guards with ease.
 * Defied: ???
 * Discussed: ???
 * Conversed: ???
