Missing door or present guinea pig, which is better? Too bad there wasn't anyone with some sort of time (or duplication) magic or something in between, then we could have had both.

Good point, its easier and more fun to retcon the door. Plus Yon just showing up inside the room with the door still there is more silly.

So retcon 2: the guinea pig is once again eaten and spat out. We are five retcons away from Yon being a lizard boy from the Sun.
