On break the targets w/ Yoshi, how do you smash the 2 bottom targets?

To destroy the one on the upside down U shape, you need to stand next to it, near where you start from and use Yoshi's Tail Spin (Down + A) as written above. I HAVE JUST REALISED THIS MAY NOT ALWAYS WORK!!! INSTEAD USE YOSHIS HEADBUTT TI THE SIDE either R + Right or A + Right.

To destroy the one on the upside down V shape, fall of the moving platform which goes towards the V shape when it is at its closet point to the V shape. Then jump into the V Shape and as you fall, use Egg Bomb (Up + B) to destroy the target. (NOTE: THIS TARGET MUST BE THE LAST ONE YOU DESTROY)

His A+v attack is best used here.

Just jump down and fly back up when you got them.

This works every time after you have practice: go to right edge above the last targets, stand on the edge with you're back 2 it, jump once and 2 go off and jump again 2 get under the platform and just
Regularly hit in anyway except with the egg, fall down against the edge of the the V and and when you get 2 the bottom of the V throw an egg really hard straight up and you should get it, it may take a couple of tries

You can use his side smash
