Marching Milde

Marching Milde is a small ball that hangs out in groups and walks back and forth all throughout Yoshi's Island. Simply stepping on them will make them pop, but you need to Ground Pound the larger ones.

A massive Marching Milde is the half boss of World 4. You must Ground Pound him to make him split apart into two. Keep on doing the same strategy against all the other Mildes.
