Dynorphin and Secretin

Dynorphin appeared as a snake. He explained that he can act as a painkiller, causing numbness where there's pain, and is particularly useful to call on when a person has just been hurt. However he can also be used to cause pain or rather make people aware of pain. Dynorphin is also responsible for appetite control and temperature regulation. Secretin appeared as a pair of eyes. She explained that she helps to regulate the stomach and pancreas, specifically the production of digestive fluids, and also helps with damaged connections in those areas of the body by providing lubrication for them.
