Amu-Aa
Amu-Aa (also known as "eater of the donkey/ass", or "eater of the phallus") is one of the gods that goes with Osiris during the second hour of the night.(To learn more about the hours of the night, see the article on Amduat.)
Amu-Aa would eat the bread made for the boat and use the perfume.
While Amu can translate to Devourer and Aa to Donkey/Ass, Amu was also used in terms of knowledge like "To Know" and Aa also means door.
