What happens to creatures in extradimensional space items if those items meld into a creature via polymorph?

[deuxhero]

Where do they go? What happens if someone tries to exit?

[Fuzzy-Wuzzy]

Like if a wizard puts their familiar into a bag of holding, then polymorphs with the bag on their person? The familiar is still in the extradimensional space, with (IMO) no way out---and a finite supply of air.

[deuxhero]

Yes. That example is more or less what I was thinking of.

That's what I imagined it would do, but wanted to know if there was any real evidence for it.

[Curghann]

Simplify the question a bit.

What would happen to an inanimate object in the same extra-dimensional space?

Likely nothing would change, unless the item specifically has a way for things inside to get out. Any function like that would be made inoperable much like being able to add to and remove items from the outside would no longer work while polymorphed/shapechanged/etc.

They'd be stuck until the polymorph ends. If someone is using the old hide in the Bag of Holding trick, then this will indeed be a problem as their air will run out.

Worse, PAO the bag into a living creature and have a cat inside a mouse. :)

I'm not sure if the wording was kept in pathfinder, but in D&D 3.0 it stated that if a living creature forcefully exited a bag of holding or similar item. It would destroy the bag and cause the creature and the contents of the bag to be expelled into the ethereal plane.

I guess it's better than suffocating.

That did not make it into PF. If something in a bag tries to claw its way out, the bag ruptures, but not to the Ethereal.

If a bag of holding is overloaded, or if sharp objects pierce it (from inside or outside), the bag immediately ruptures and is ruined, and all contents are lost forever.

This mostly still happens if the creature tears the bag from the inside, though it says the contents are "forever lost" without specifying a plane.
