I thought of a few small ideas, some related to reading the threads here and a few of my own.
In our homes we have fire places so could we have a fire?, Perhaps using wood/peat as fuel, lit by using a firefly. In a warm house you would slowly recover mood and/or energy.
Possible new combos,
Pig + Butterfly = Flying Pig - flies away but ups your mood
Pig + Firefly = nice sizzly bacon sammich - ups your energy (well I'm hungry)
Pig + Hen = Mighty Meaty Ore - not sure what this will do lol
Hen + Hen = NowHen thats funny - eggstra xp for the next 5 mins.
Fireflylight like a flashlight for dark places
GetoutClaws to escape from Hell, thinking these would take a lot to manufacture and only be available later in the game but mean you dont end up in hell if you died/ or possibly let you escape from a cage/ prison /Rook Trap,
well thats it for the moment. I think I need sleep
