How do you do ice breakers the event?

Event Match #21: Ice Breaker as whoever you're the best with.
This one is quite tricky - out of the four Ice Climbers (2 Pairs) you need to KO the 2 Nanas (the Pink Ones); KOing a Popo (a Blue One) will Fail the Match.
Since all they do is jump up and down - use that to your advantage - go hit a Pair to separate them and then attack the Pink Ones!
Good Luck wasupdog =)

You should use a weak attack to knock them away. Hopefully, their jumping pattern will be disrupted. If not, try again. If so, run and grab Nana (the pink one), throw her away from Popo (the blue one), then attack and smash it as much as possible before she gets back to the other. When you're done with one, hurry and attack the other in the same pattern.

Try separating them first.

What I did is I selected young link. The pink one always jumps slower than the blue one, so what I did is got height, did his double jump and downward stab on the pink one ( down A). Then, try grabing her. Once she has some damage, use his spin attack on both of them (up B). She will stay longer because she has more damage. When she's alone, give her a beating and repeat the process on the other one. It takes a bit of luck too.

Good luck!

I used DK and won. Use the Z button to grab
The pink one then press < or > (whatever way you
Are facing). Then throw her off the edge. If she
Jumps back up jam the control stick and the
A button (clap) to kill her ONCE and for ALL!!!

I used Marth, I would grab the pink one and toss it to the side then charge b and hit it before it regroups with the blue. It took a while to get the hang of it but once I did it was pretty easy to do.
