This lava bad ass is made by Troy Stith. It’s based on a Jouwe (strange name) and was for a show for Toy Art Gallery. He even  made some flavor text.

Although there are many destructive giants roaming the fields and forests of Tu’R’Land, Mafic reigns as the king of annihilation. With an unlimited source of growth underfoot, Mafic can double and triple in proportion at will. Stomping and absorbing villages with delight, he leaves mighty kingdoms as little more than glassy memories in his trail of terror.
