Belching Snakes

We were driving in the car recently and my son asks, "what would happen if snake came out of your mouth every time you burped?"

I think a normal parent would have reacted much differently than I did.

"What kind of snake?" I ask.

"Well, if you burp once, a spitting cobra comes out. If you burp twice, a king cobra comes out."

"What happens with the cobras when they are out?"

"The cobras will do whatever you say or just follow you around for a while."

"If you burp a lot, do you get a lot of cobras?

"No, you can only get three cobras no matter how many times you burp."

"What if I burp three times?"

"Nothing. One burp is a spitting cobra, two burps are a king cobra."

Thus we have the belching snakes spell for Swords & Wizardry or your favorite retro-clone.
