Where did Menthuthuyoupi's eyes go?

Question

In episode 116 of Hunter X Hunter 2011 we can see Menthuthuyoupi aka Youpi in the begining, but where did all the eyes that where covering him go ? We can still see the gray spot that was supposed to cover one of the eyes but non of the eyes seem to be there.

Answer 1

As an Enhancer, Youpi's ability "Metamorphosis" allows him to shape-shift at will⁽¹⁾ (such as giving himself wings, as seen earlier in the series). This allows him to hide and reveal those eyes at will.
