Cuoxur

Cuoxurs are probably the oddest creatures found on Sejan. In addition to their highly unusual shape, their means of defense and reproduction are strange, to say the least. To fend off enemies, they use disorientating, highly damaging sonic attacks that vibrate the air and leave ringing in ears of those in vicinity for dozens of minutes.

Their way of procreation is even more unique: All Cuoxurs have many tiny little cavities on their tops. During mating, they rub their backs together and release ooze from these pores that then forms into the shape of genitals. It is currently unknown if one retains its sex or can switch genders, but the former seems more likely; however, more research is necessary.

Miggpli's research
Miggpli asks the player to tag the Cuoxurs with colored Amoul shells so that he can distinguish males and females during observation. The player is tasked to get close to them, 'excite' them and tag two and two of each sex accordingly. This requires a combat sequence for each unless the player takes advantage of falling into/entering a Cuoxur pit.

Cuoxur pit
While traveling through the Sejan forests during the day, there is a small chance to fall into a pit filled with sleeping Cuoxurs (they are nocturnal creatures). Those pits are built by Cuoxurs, with leaves, sticks, and loose dirt glued together with unknown fluid. This includes the ceiling, so a human can find themselves falling through it.

Players who don't have info on them from Miggpli can only climb back out. Those who are knowledgeable on them can decide to start 'exciting' the creatures and possibly engage in an orgy.

If the tagging quest for Miggpli is active, the pit can be used to tag all required Cuoxurs at once. The chance to randomly stumble upon the pit is also much higher during the quest.
