What items can be changed into other items when used?

Question

Is there any list of the items which can be "open"/ changed into new (random) items?

I know about few of them like, however, I am sure there is much more:

You see a shiny stone.

Something precious might be sealed in it.

You see a surprise nest.

Use it to get a little surprise.

You see a medicine pouch.

You see a surprise bag.

You see a surprise bag.

You see a surprise cube.

There might be something valuable inside.

You see a surprise jar.

You see a gooey mass.

Perhaps it contains something useful.

You see a lot.

You see an unrealized dream.

You see mysterious remains.

You see a gnomish supply package.
