The acid bug comes from a Nofruit that is whacked at precisely the wrong time.
Looks
It is pink as a female and dark blue as a male. They have beady eyes, horns, and six to ten legs. They also have a huge mouth with a tiny throat.
Behavior
When a nofruit is whacked at a certain time, it will produce a bug. The bug will leap at whoever is closest and suck on their face like a leech. They can also communicate by spitting at each other.
Mating
The male and female will spit at each other and then begin sucking each other's faces, in a way that looks like kissing.
