Bad Vibe

Found on the Green Evil Planet, the creatures on it were physical manifestations of antisocial behavorial transferals of latent intentions of maledictions against other sentient beings. Or as Zooz translated for Zool, a "bad vibe".

Other creatures like the flying mushroom were other bad vibes. The one featured in the picture to the right was a bad vibe that Zoon tried to eat and Zool had spit back out. (1)
