The first step of obtaining the Folded Datta Glutton is defeating the Sandbelching Meerslug. This can be a time consuming task, so it is recommended to spend one day fighting the boss and retrieving the objects. If this is the first time you are fighting the boss, it may take you a few tries. Use Bomb Rocks and Ultra Spicy Sprays to speed up the process. Once it's dead, proceed to bring the Glutton, and, if low on juice or Pikmin, you can also bring the Crimson Banquet or the Sandbelching Meerslug's body with you.
