Mayan Sacrificial altar and demon hatchery

An idea I had for a design of a hatchery. This is based off mayan culture. A sacrificial altar lets the blood of the sacrifice seep into the building which in turn flows through the hatchery in all these different pods. The blood is used to feed and grow a hybrid of owl/bat demons. The hatchery is based off the aesthetic of corn, and when the demons are about to burst from the pods, it looks like popcorn. The altar is supposed to be designed as a skull, and the owl of the god of the underworld, Ah Puch, is in front of the sacrificial altar.
