In New Donk City, there is a group of people playing with a jump rope. Mario can join in to try and earn a high score.
After winning a moon for achieving 30 jumps, a nearby man said "I wonder if anyone has ever done 100 jumps...". I'm not sure if this was simply encouraging me to get a high score, or if this was a specific goal I should aim for.
Is there a reward for getting 100 jumps in the Jump-Rope challenge?
