Nidofarig's tail is significantly more aggressive than the main head and it will try to prick anyone who passes by with its poisonous horn. The main head however prefers to peacefully graze on grass and ignore the tail's actions.
A Nidofarig is an herbivore--it eats grass and tree shoots. Its highly toxic barbs are thought to have developed as protection for this small-bodied Pokémon.
