King Dedede, for once actually doing the best for Dream Land, orders the monster to make sure that the possessed Kirby doesn't cause damage around Cappy Town. At the last moment, King Dedede allows himself to be possessed by the Demon Frog, but then Heavy Anaconda appears and eats the Demon Frog. Knowing that Heavy Anaconda is extremely ferocious and shouldn't be wandering around, Meta Knight throws a torch to Kirby in an attempt to help him defeat the huge snake. Kirby eats the torch and gains the Fire ability and burns Heavy Anaconda to a crisp, destroying it.
Heavy Anaconda, unlike the monster with a similar name, isn't a robot. Instead, Heavy Anaconda is a huge brown snake with a tan underside and a spotted pattern running across its back. It has glaring yellow eyes and pale yellow markings running along its long tail. The snake is able to swallow virtually anything whole, and its fangs are extremely venomous.
- In Japan, Heavy Anaconda is actually a pun. The Japanese word for heavy, "ヘビー/hebii", is similar to the pronunciation of the Kanji "蛇/hebi", which means snake and/or serpent.
- Heavy Anaconda is the only monster Fire Kirby doesn't spit fire at (instead, Kirby uses attacks seen in Kirby Super Star).
