One Green Monolith (Randomly spawns for each game).Although originally a terrain glitch, the Mohole (a large, steep vertical 'tunnel' at Moho's north pole) is often considered an Easter egg, and indeed was later 'canonized' by the developers, being given its own biome (the 'Northern Sinkhole') and KerbNet anomaly marker.This does not include bugs like terrain glitches. In Kerbal Space Program, this corresponds to any anomaly that has been hidden in the game on the surfaces of bodies in the Kerbol System the Main Menu, in IVAs, and any other applicable area by the developers. An Easter Egg is an intentional inside joke, hidden message, or feature in a work such as a computer program, video game, movie, book, or crossword.
