Peanoids at the time were supposed to be made of real living peas, like how beanoids at the time were made of living bean matter, so if we're going off of the old canon peanoids they'd be just as edible as a normal pea, but by how things work now, peanoids would probably just be green colored mammals, or perhaps even reptilians, so idk. Depends on what canon we're going off of when thinking about peanoids. Idk whether they'd be made of pea, mammal or reptile rn
