Like Beanbon, Big Beanbon appears to be a vegetable root of some sort, with a green, bulbous body and twin leaves on its head and orange feet. Its face is chubbier than Beanbon's. Big Beanbons seem to wear orange lipstick, which is the case with the Big Mummbon as well.
Big Beanbon acts like its smaller counterpart. It is more dangerous to the Kirbys as it shoots larger explosive coconuts and takes less time between shots. If it happens to be on a ledge above a Kirby, it attempts to leap onto him. If it lands a hit, the Kirby is squashed and instantly KO'd. Due to its size, Big Beanbon is able to effortlessly shake off Kirbys that grab onto its body; it must be overpowered by a large swarm or repeatedly attacked by a small group to be defeated.
