List of easter eggs

There are numerous anomalous formations on the surfaces of bodies in the Kerbol System. Some remain undiscovered as of today.

Kerbol

• None known

Moho

• There are large, steep vertical "tunnels" that could be considered easter eggs, and anomalous forces are present around the rim of each tunnel.

Eve

• None known

Gilly

• 0 degrees, 0 degrees, there is a perfect square pyramid.

Kerbin

• Five Monoliths
• Inland Kerbal Space Center
• Memorial to the Mk1 Command Pod
• A temple in the desert - Underground as of v0.22 - Reappeared as of v0.23
• A crashed flying saucer on northern ice cap
• Scorched Mk1 Command Pod, Liquid fuel tank and LV-T45 rocket in a hangar on the Insular Airfield
• At the exact north pole, there is perfect square pyramid which flips Kerbals randomly. This is not really an easter egg, but is a product of glitches in terrain mapping.

Mun

• Three monoliths
• Three mun Arches
• Neil Armstrong Memorial
• Crashed Flying Saucer

Minmus

• One floating monolith

Duna

• Giant Kerbal face
• The camera which looks like that of the Curiosity rover, buried in the soil (appears to be underground, as of at least 0.19.1)
• Hill making SSTV signal (source of signal now several hundred meters beneath hill as of 0.22)

Ike

• Magic Boulder - There is a monolith on the boulder. Boulder contains strange clipping boundaries that can result in your ship exploding seemingly spontaneously. It also seems to glow green as if it is radioactive.

Dres

• None known

Jool

• None known

Laythe

• None known

Vall

• Stonehenge formation in the southern hemisphere

Tylo

• Crater with Carl Sagan's face
• Cave-like underground formation

Bop

• Dead Deep Space Kraken

Pol

Eeloo

• None known.

Overall

• While not easter eggs per se, the exact geographical poles of most bodies have highly unusual topography, usually making them inaccessible.

IVA

• Some of the cockpits have post-it notes and other humorous writings inside them. The writing is somewhat blurry and hard to read, but still legible. For transcripts of the notes, see the respective part pages.

Parts

• On the Z-100 and Z-400 Rechargable Battery, the logo claims the batteries are Batt Man Batteries. This is a reference to Batman.
• On the Communotron 88-88 is the hexadecimal number 0x62656570. When 0x62656570 is converted to ASCII it spells "beep".
• Also on the Communotron 88-88, is the serial number 04101957, which is the launch date of Sputnik 1, 4th of October, 1957.

Loading Screen

• While not that much of an Easter Egg instead of a reference, the loading screen makes a reference to The Hitchhiker's Guide To The Galaxy, stating "Answering Ultimate Question" one of the well known phrases from the book.

Main Menu

The Mun dust castle.

• One of the two main menu images is that of a Kerbal standing on the Mun's surface, with Kerbin in the background. There is a 1 in 40 chance that a sand castle made of Mun dust can be seen at his feet.

Scenarios

The Kerbal XX orbiting Duna's moon, Ike.

• During the Space Station One scenario, by zooming out far enough to show the planetary map, a ship by the name of 'Kerbal XX' can be seen orbiting around Ike in a sub-orbital polar orbit.
