This article is about the speedrun. Were you looking for the game mode planet D?
Planet D is a speedrun in the Dino Run game. It is only unlocked after you beat the Insane Challenge. In the last level of the Insane Challenge, the aliens save you and the other dinos in a giant UFO that brings you to the aliens' planet. On Planet D, the gravity is lower and the boulders are balloons, save for one like the one you need to take to get to the T-Rex Egg . You can still get Planet D if you completed the Insane Challenge with all cheats on. Up to 3 (!) Super Eggs can be found on. Many large dinos; like triceratops, trundle about in large herds.

This level. This is the longest speedrun. Also despite being a supposed safe haven, the Wall of Doom still exists. Oddly, there are no aliens here despite being their aliens' planet.

Chaos
The more difficult you choose the speedrun to be, the bigger the chaos is. On Insane, there are critters, large dinos, eggs, meteorites, and balloons flying everywhere, making it harder to navigate. Sometimes there are so many rocks and dinos you fall through the floor and have to restart, if you go in one of the narrower tunnels. This is also where it is most likely to see lizards and large dinos walking through walls.
