In his latest plot to get rid or Kirby, King Dedede is given two captive twins from Popstar’s South Sea by NightMare Enterprise who can summon a giant caterpillar monster named Mosugaba. This monster is the protecter of the South Sea Island where the twins were captured from. The arrival of this monster causes everyone to sneeze from it’s pollen (including Kirby later on). When Mosugaba spins his cocoon near King Dedede’s castle and evolves quickly (thanks to King Dedede, Escargoon, Waddle Doo and the Waddle Dee trying to destroy the cocoon by fire) into a butterfly. It’s wings emits dust that causes coughing problems for Kirby and King Dedede. Escargoon, tired of the dust and pollen problems, tells Tiff and Tuff where King Dedede’s keeping the tiwns and Tiff and Tuff rescue them. The Twins do their hula which stops Mosugaba from attacking Kirby and the Twins and Mosugaba fly off and return to their island in the South Sea.
