Suspicious Dirt Piles are naturally spawning objects. They can be found randomly in the world and will change locations if players are more than 200 metre away. Once examined, the Suspicious Dirt Pile will be uncovered by the Character and replaced by an Animal Track pointing in the approximate direction of travel. Another pile of dirt will then spawn 40 metre away in that approximate direction. There is a ±30° difference in the actual direction compared to the direction shown by animal track.
Upon uncovering the final footprint (there can be between 6 and 12 per hunt), the character will alert the player that the creature is close. A Koalefant or an Ewecus will be spawned rather than another track. The chance for spawning an Ewecus starts at 5% on Day 1 and increases gradually to 33% on Day 100. The mob will remain in the world until it is killed, regardless of which Seasons pass.
The track will disappear after 37.5 seconds, terminating the hunt. The track will disappear after 22.5 seconds if there is rain or when the world wetness is more than 15. Player has to wait 5 seconds after their track has washed away before a new set tracks will spawn for the player.
There is a cooldown of 432-720 seconds after completing a hunt
In the Reign of Giants DLC, Suspicious Dirt Piles have a 50% chance to lead to a Varg instead of an Ewecus. As such, on day 100 there will be a 16.5% chance of spawning an Ewecus and another 16.5% of spawning a Varg.
