There's 3 "boss" fights at the manor. The duchess, the boss inside infinite food (pregnant cake), and infinite food itself. To fight infinite food, the duchess has to be dead or imprisoned. It's not a particularly interesting or rewarding fight though.how do i fight the boss in the duchtes mannor i have hidden body and suspious meat was i to late by being at progress 10 yet the chesire cat is still at the bonfire so there must still be something here to fight
