Flamin' Golems are fire-based Rabbid/Golem enemies that appear in Mario + Rabbids Sparks of Hope, specifically in The Last Spark Hunter DLC. They first appear in the The March of the Golems battle in the Melodic Gardens. They bear a slight resemblance to the Icicle Golem from Mario + Rabbids Kingdom Battle, but are smaller and are real Rabbids instead of being completely composed of rocks. They have volcanic rocks on them, with lava visible on their shoulders.
