Lucky Isle

Lucky Isle is an island located on Lake Lapcat in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury that appears only after the main story has been completed. It is a small floating island containing 5 Cat Shines, and Mario can only collect one of them at a time before it disappears. The island shows up every time Fury Bowser is present, disappearing as soon as either Mario collects a Cat Shine or Fury Bowser goes back into slumber.
