Hmm... Well, you see, Kirby is said to be an amoeba, a single-celled animal that catches food and moves about by extending fingerlike projections of protoplasm. Amoebas are either free-living in damp environments or parasitic. an Amoeba reproduces asexually through binary fission. In this process of reproduction, a single amoeba is divided into two similar daughter cells. They are genetically identical to each other. So, Kirby would have to divide himself into two of himself, so he would have two others that look like him.
