Here’s a few of the items you can find hidden away in the game that will have varying effects on your playthrough. They have a fairly convoluted path from being comprised of an adjective / noun that’s interpreted (by me) into an object that has a related trait or effect. For example:
“Frozen” “Keech” (An old word for fat) becomes the chirpy little snowman who will be a reuseable item that you can drop in the environment for makeshift cover.
“Dextrous” “Hedgepig” is the ring/keychain that definitely in no way, shape or form is a nod to Sonic the Hedgehog. (Or the fact it makes you drop precious currency when you get hit!)
