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.
• In the ocean just south of the KSC, about midway between land and the southern ice cap, engraved into the ocean floor is a giant smiley face, best seen from orbit or on a topograph.^{[citation needed]}

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. (M.I.A. since v0.18.)

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

• None known

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.
