Mario + Rabbids challenges aren't easy

Says the challenge is easy, that isn’t true. Maybe if you unlocked the thing that lets you dash more then one enemy, problem is, you need power points or whatever to get it, you can get those by doing challenges, and the story. Easy for smart people. Giving me only three turns to kill 14 enemies.
I failed more then once, once all three characters died, it was the last turn anyways.
