To clarify on the infinite mouth loop thing is:

Manifesting multiple mouth features within the stomach that are all always open except for one hidden one. The hidden one is the one that is actually connected to the ozodrin's throat for the purpose of escaping swallow whole. The rest are actually randomly connected to each other, so that no matter which one you go through, you eventually reemerge in the main part of the stomach. Imagine a large room with multiple doors and a hidden trapdoor in the ceiling. The hidden one is the way out. The obvious doors each connect to another door through a series of passageways and stairs, and some doors lock randomly behind you or while you are in the main room. Would that be possible, and if so what would the effect be?

So, basically, you can fit 4 swords or 2000 gp for every one halfling?
