Just run one and you’ll be good for the cash reward
Super Mario Bros. 35 is still going ahead and Nintendo is trying to push people back into the free play (with Switch Online, for that one person who will state it’s not “free” in the comments!) affair with events. As it progresses to its impending March 31st expiration date (still can’t believe this) you can dive in and kill some Goombas for fun and profit.
All you have to do to get credit is kill just one Goomba in the game, but together everyone has to wipe out 350 million of them. The event currently runs through Monday, March 1 at 10:59 p.m. PT. Below are the full details to be sure you are ready to go!
This is actually the second event to award bonus platinum to My Nintendo members. Recently, Nintendo held a very similar activity that also earned people 350 points, it just involved killing Bowser.

When the goal is reached, all participating accounts that have beaten at least one Goomba during the event period will receive 350 Platinum Points ** which can be used in the My Nintendo Rewards Program.
