Like Big Beanbon, Big Zombon resembles its smaller counterpart. Unlike Zombon, it is chubbier and its leaves are more shriveled.
Big Zombon appears exclusively in Volcano Valley, specifically in Stages 4 and 5. It attacks the same way as its smaller counterpart, by shooting red globs of poison at the Kirbys. If a glob hits a Kirby, he is encased in it; rises into the air; and, if he is not freed by the player, transforms into a Zombon. The zombified Kirby can be defeated to return him to normal--otherwise he burrows into the ground and is lost.
Like other large Beanbon variants, Big Zombon fires three of its projectile in quick succession. Like Mummbon and Zombon, Big Zombon revives itself shortly after it is defeated.
