From their announcement:
Son of Gourdzilla was born during a battle between Cthulhu and Gourdzilla when the Cosmic Entity severed a large portion of Gourdzilla’s corporeal form and it fell to the ground, writhing. Lightning struck the limb and it immediately grew into a new monster! Feeling a kinship with Gourdzilla, Son of Gourdzilla often aides his father in battle as a bodyguard.
Son of Gourdzilla requires BRCSD901: Kaiju Kaos – The Miniatures Game (Basic Rules).

This 4 piece resin kit includes an integrated Size 4 (4 inch diameter) base and stands approximately 5.75 inches tall from top of the head to bottom of the base.
