They are born under water then turn into Larvae.They then turn into adults after their hard skin has peeled.
Usually their skin will turn rosy red when you hit them, but can turn blue and purple if you hit them hard enough.
Depends if the yellow people have some sort of skin disease, which is transferable then it is possible.
It makes their skin turn purple then bugs get attracted to it and eat it to death
