Cool World/Fridge


 * Fridge Logic: Knowledge of various Doodle/Noid interactions and their consequences are extremely widespread in Cool World, but aside from one or two throwaway lines about what Holli's been up to lately, Frank and Jack are apparently the only humans who've even been to Cool World, let alone know it exists.
 * Debatable as it's implied humans have lost it and come to Cool World, they usually just don't last very long.
