Ludivoir uses plant stalks as makeshift microphones, singing into them as it dances about rhythmically. Those that don't willingly join in the dance will be manipulated into forcibly dancing through its psychic powers.

It apparently does not feel the pull of gravity because it supports itself with psychic power. When it hears festive music, all the cells in its body become stimulated, and it begins moving in rhythm.
