Ok - bear mode activated: I'll add 'The Star Bear' by Michael Swanwick, where a man's series of encounters with a bear in Paris echo his feelings about being a Russian emigre.
You saying “bear mode activated” reminds me of Dicey Dungeons...
(For those who don't know, there's a place in the game where, with a moderate amount of luck, you can trigger an item that transforms you into a bear, which changes your stats and available equipment, and you remain that way for the entire rest of the dungeon)
