Event 22: Super mario 128

You have to kill 128 Tiny Mario's in this event. Each of the Mario's are tiny so they weigh less and thus are easier to kill. They are smaller too. Mario's will start coming down three at a time. As the event progress, four to five Mario's will come down at a time. This event is tedious so items like the Warp Star and Pokeballs are helpful since they can kill multiple Mario's.

Strategies
Donkey Kong

Use Donkey Kong's down B move to kill the Mario's. Try to stay in the middle of the stage too. Also, beware of explosive items while using this move.
