Toon physics

Toon physics are rules of how the universe works in cartoons. While most of the characters in the Scooby-Doo universe are relatively realistic, others have a higher degree of "tooniness" which gives them what amounts to super-powers.

Scooby-Doo possesses this ability to a high degree, and so do other talking canines related to him. Shaggy Rogers has a slightly lesser power. The rest of the gang has only mild tooniness.

Rules of toon physics

 * Gravity has no affect on a character unless they look down and become aware they should fall.
 * Fear cancels gravity. A scared character can leap to arbitrary heights.
 * Rebounds increase momentum.
 * A running character can crash through any wall, leaving a silhouette conforming to their outline.
 * Characters can contort and fit into any container.
 * Inflating someone with air can make them balloon out and become lighter than air.
 * Releasing the pressure on something filled with air converts it into a jet-propelled rocket. The flight will inevitably land on the villain or do something funny.
 * Characters can produce arbitrary objects from thin air, or "hammerspace."
 * Creating a situation with disguises will fool the smartest villain, at least for a short time.

Shaggy sometimes demonstrates knowledge of Scooby's powers and treats him a bit like a genii. For example, when they were being chased by Vikings in a hand-car and needed a way to escape, Shaggy asked Scooby to "think of something" that would help. Scooby produced a flying bicycle from hammerspace that they used to fly away.
