From the Super Mario Wiki
Final Butapoppo (ファイナルブタポッポ) is a giant Hawg that appear in Donkey Kong Jungle Beat. They are mounted by Ghastly King and Cactus King at the beginning of their battles. They spit a continuous stream of fire out of their snouts. Donkey Kong must use the Sound Wave Attack to deflect the flames and eventually stun them by doing so. He can then attack the stunned Hawg by punching it; it takes fifteen punches to defeat it. After doing so, the kings destroy their mounts by landing on it. Their defeat is a likely reason for the 800 beats gained at the end of the battle.
