You realize that it must be an Ogre that is coming toward you, and the ruthless Ogres of the mountains are known for feeding the living to their children. Ogre children are normally adorable, but not when they are nibbling the spare limbs of a screaming victim. Egad.
Suddenly it hits you. You know exactly what to do! You can use science to defeat the savage beast. With oil and orange juice you could make napalm... If only there were some orange juice around.
Excellent! It appears that you do in fact have a small amount of orange juice in the pocket of the magic pants you forgot you were wearing. You whip up some science magic, and before you can say "isn't that convenient" you have constructed the weapon of fire.
Except you weren't wearing pants... you had no magic orange juice pocket...
What's happening to me?
You're being eaten. Slowly, but still eaten. The monster that came for you was the Antagorax, a giant spider-demon who prowls the highlands. Before it kills its victims, it doses them with a powerful hallucinogenic gas. When under its effects, a person does not even realize they are being eaten until they have lost too much tissue to maintain brain function. The Antagorax started on you some four hours ago. There are worse ways to go.
You're dead.
