Hundreds of rooms access items

I seem to have accumulated hundreds of corels, gravitons, energy cells, tusks, shields, runestones, cannonballs and containers from somewhere, not that I'm complaining but just wondering where they all came from, I have over 600 of each along with hundreds of snatchin banishing items including over 500 bookworm hooters.

Anyone have any ideas

Have you been completing any of the achievements ?? sounds like you have received some of the chests that give you the room unlocking items and the banishing items
