How do you beat event 51?

Lots of people have trouble with this event. You're not the first, I assure you. If you want a quick, cheap win, try executing Jigglypuff's Rest move to send them to an early demise. You could also hover over the edge of the stage hoping that one of the three fools will take a jump at you and miss a chance to recover back to the stage. Or you could just keep trying with the character you are most comfortable with. I've always thought that's the best stretegy. Nevertheless, just keep trying. You'll beat it eventually.

The easiest way to beat the event is to take jigglypuff. Run away to the left and wait for the bad guys to start following you. Start to jump, get hight and go right into Giga Bowser and when you're touching him, do your down B attack. Keep using only that attack in the air whenever you can against Giga bowser until he's dead (it should take about nine hits with down B). Try to have him die before you lose a life. It's really important to avoid the enemies' attacks because with any damage at all, Ganon and Mewtwo can both kill you. Once Giga Bowser's dead, all you have to do is beat Mewtwo and Ganon regularly. A piece of advice: if you suck with jigglypuff, just act like a scaredy cat and wait for items. If a item like a bat or anything that can be used to swing comes (especially a lipstick), get it before Mewtwo because or else he'll own you with it (he'll hit you like ten times in a second).

Make jiggly puff go to sleep while your right next to giga browser

Use Jigglypuffs B-bown move whenever you touch Giga Bowser, and he will die in no time at all. For Mewtwo and Ganondorf, just avoid them by jumping from one side of the stage to another until an item like a pokeball appears. Make sure to keep your distance from Ganon and Mewtwo, and use items when you can. This may take about 6 minutes to beat, but it is the best way. Thank CR, ok?

It's a tough one, no doubt about that, but it's the last one, so keep practicing and keep trying - when you get it done - you'll be completely done and feel great about it lol!

Some tactics...
- Try using Jigglypuff! Why you ask? Because by using her Down+B move, you can KO Giga Bowser at a low percentage if he's near an edge.
- The idea behind Jigglypuff's Rest move is that when you're above an enemy and you use Down+B, if you're directly aligned with that enemy below you, it'll hurt them significantly.
- I've also done this Event with Yoshi - jumping above everyone and getting some height keeps you out of danger for a little while.
- Then use his butt stomp (Down+B) to inflict some damage on hopefully more than one character.
- REPEAT!

- Get rid of Giga first - he's the biggest and the biggest pain!
- You can deal with the other two once Bowser's history.
- Using Items before your opponents is also key!

GOOD LUCK - YOU CAN DO IT =P
