Golden Pyramid can refer to two things, both from the Game Boy Advance game Wario Land 4.
1. Is the Outer Pyramid that is raided by Wario, which is seen in the opening cutsceen (refer to picture). Wario raids it because the in-game rumour is this pyramid has a large amount of treasure inside. He them gets stuck inside the pyramid after falling down a crevice.
2. The Inner Pyramid is in the middle of the main room in the game. It is protected by five passages: the Entry Passage, Emerald Passage, Ruby Passage, Topaz Passage and Sapphire Passage. Upon completing all five, Wario could enter the Golden Pyramid itself. It contains one level, the Golden Passage, with the final boss, the Golden Diva following that.
Trivia
- The Pyramid made a small minor appearance in WarioWare: Twisted!, as a picture in the opening cutscene, along with the Music Box from Wario Land 3.
