Pis forPoisonous

Something is poisonous if it contains poison. Poison can make you very sick, or kill you. Poison needs to get inside you somehow to be dangerous. Poisonous mushrooms and berries are usually eaten, and poisonous insects and snakes inject poison when they bite you. The frog in the picture will poison anything that eats it, and people use the poison from the frog to put on arrows and darts to help them hunt.
