From WiKirby, your independent source of Kirby knowledge.
Burner Guardian is a massive golden snake statue which serves as a stage hazard in Kirby: Triple Deluxe. It can be found in Stage 4 and Stage EX of Wild World. Burner Guardian is intangible, and cannot be interacted with.
Burner Guardian resides in the space between the foreground and background in the areas where it appears, and continuously pivots to face Kirby, tracking him as it moves. It regularly shoots fireballs from its mouth toward Kirby's last position, waiting three seconds between each volley. Burner Guardians often appear in rows together, making traversal through the areas they inhabit very dangerous.
