This is actually a story I made on FanFiction.net. I just wanted to share it on DeviantArt for fun.
This part of the story is told from the perspective of Bowser Junior's friend, a Hammer Bro. named Craig.
First off, Bowser Junior was about to enter his room when his dad came in. He told him, "You mostly eat junk food all the time." Bowser Junior told him, "So?" "How about you do something to get rid of this?" "What, Dad?" "Exercising!" "What is exercising?" "Well, it's a bunch of sports that keep you healthy! So?" "I'll try it soon, Dad."
Bowser Junior fell on his bed, thinking about what his dad told him to do. He tried and tried, but he couldn't choose from a category of sports. I came in, and told him, "What's the matter Junior?" Bowser Junior told me that Bowser told him to exercise, but he couldn't choose anything. I suggested that he should rather go swimming, which Junior accepted.
Later, Junior was at the pool with me and a Koopa Troopa. Junior was wearing a swim ring
