This egg was only available in Egg Cave's Cash Shop Park for May 2014.
Wigglet eggs may look soft and hug-able, however, they are extremely fragile and must be taken care of with extreme caution. They can only incubate between 31.4 and 31.6 degrees Celsius, and have very thin egg shells that can shatter easily.
Unlike their fragile egg, adult Wigglets are very sturdy and can be stepped on by an Arkian without taking any injury. Curiously, their behavior is more similar to that of spiders than millipedes. They tend to hide in corners of houses and set up their home there for laying their eggs. Once their eggs are laid, they stay on guard for their eggs until they hatch, which makes removing unwanted eggs very difficult.
The substance on its back that looks like fur become more and more firm throughout its lifetime. At adult stage, they become mildly poisonous and are considered to be dangerous, although their poison can usually be easily cured at a hospital. Due to this, Arkians find the Wigglet to be one of the more "pesky" bugs in Ark, since once one finds its way into your home, getting it to leave is very difficult! (It also leaves the present of hundreds of Wigglet eggs behind!)
