Sea urchins are low-level creatures that can be hunted for loot.
Sea urchins can be found east of the player's workshop, all the way to the waterfall on the most eastern edge of the map. They can also be found in the grassy area near the Hazardous Ruins and the Clinic.
Sea urchins spawn from 7:00 to 17:00, and from 1:00 to 3:00. Like other creatures, they will respawn if the player enters and then leaves a building during their spawn times. They are low-level creatures, usually ranging from Level 1 to Level 5, though sometimes found at higher levels. Sea urchins found near the Hazardous Ruins range from Level 6 to Level 10, just like other creatures found there.
Sea urchins are slow creatures, with move speeds just below that of the player, but after being attacked, they will travel at a medium speed, moving as fast as the player. They travel by flying, and, like all other creatures, they will run from the player when they get close. Sea urchins, like other creatures, are able to enter water. When attacking, sea urchins will rise up and then drop on top of the player, releasing purple smoke.
Sea urchins will, upon death, drop 2-3 meat.
