It is one of the very few obstacles in the game that can't be mined with a mattock or blasted apart with bombs, but getting the Hedjet hidden within it is necessary in order to visit the City of Gold. The blocks directly beneath it are as indestructable as the Moai itself. The Moai is found on either level 3-2 or 3-3, unless the player went to The Worm and The Mothership, in that case The Moai will appear in 3-4 (after The Mothership).
