For once actually doing the best for Dream Land, King Dedede orders Heavy Anaconda to make sure that the possessed Kirby dosen't cause damage in Cappy Town. At that last moment, King Dedede allows himself to be possessed by the Demon Frog, but suddenly, Heavy Anaconda appeared and eats the Demon Frog and Dedede's hammer as well as Dedede. Knowing that Heavy Anaconda is extremely treacherous 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 and saving Dedede in the process as possible.
Heavy Anaconda is a huge brown snake with a yellow underside and a spotted maroon pattern running across its back. It also has glaring yellow eyes and pale yellow markings running across its long tail. It is able to swallow virtually anything it wants whole, and its long fangs are extremely venomous.
- In Japanese, 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 that Fire Kirby doesn't spit fire at (instead, Kirby uses attacks seen in Kirby Super Star).
