Psycho-Bugs live on the shaggy planet and dead octopus planet. By clicking or touching their antenas you can create sounds, but If you play a certain pattern of noises on them, smoke will come out of their nose and will reveal something. They don't have to have gender and they can come in different colors and sizes.
