Their heads appear to be combustible.
When Ernesti and his friends are traveling across the desert to reach Fort Casadesus, the Order of the Bronze Fang sets a trap for them. Lured by bait, a massive Shaker Worm attacks them. However, the beast is defeated by the Telestale Silhouette Knights, who use their rods to blast it to bits. With a stab from a rod, the Worm's head begins to glow and swell, before exploding.
