If you want lots of lives, first get a cape, then go to Yoshi's Island 3 (I think it's that level.It's the first level that has the rotating platforms on it).
Just past the checkpoint there are some floating yellow blocks. There is a koopa walking around on them. This is what you need the cape for.
First, jump up on the blocks(with the cape) and,when the koopa's at the edge of the blocks(the edge on the right near the wall)use the twirl(B)attack, and keep nailing the B button, and, if you keep doing it correctly, you should start getting lives.
Just don't let the koopa fall to the ground.
Keep doing this all you want.
