Poobah the Pharaoh's Pyramid is a location that appears in Wario: Master of Disguise.
As the name states, Poobah the Pharaoh's Pyramid is a large pyramid with many artifacts around and Egyptian-themed enemies such as living coffins or sphinxes. There are also many hidden doors around that requires the use of Genius Wario to uncover them.
Picking the Pharaoh's Brains
Wario and Goodstyle continue their quest for the Wishstone pieces and were led to Poobah the Pharaoh's Pyramid. After going through the many secrets of the pyramid, they make it to the Royal gatekeeper who asks Wario to gather the two royal medallions after the latter was rude to the gatekeeper. After doing so, Wario was able to meet Poobah the Pharaoh himself and defeat him in battle.
It was also revealed how the pyramid came to be. 5,000 years ago, Poobah called upon a demon to grant him a wish and the demon would only do so after Poobah agrees to stare his people. Poobah agrees but the demon turns on him turning his whole palace into a pyramid and burying him deep underground.
