“A simmering pot of sinisterness.”

    —Skystones Overdrive flavor text

Cauldrones are silver living cauldrons with sinister faces that lurk in the Vault of the Ancients. They fire the concoctions inside of them as an attack. Like Muck Yuckss and Energy Guardians, Cauldrones are affected by Push and Pull, changing color and being frequently moved off of the platforms they use to attack from afar.

They made a reappearance in Skylanders: Imaginators, inhabiting Nightshade's hoard in the Sensei Dark Realm.

Trivia

• Because their only appearances in the Vault were either in shadow or in range of the magnetic magic, their original color can only be seen in their Skystone. Their silver plating can be later seen in Imaginators, as they are in areas open to the sky.
• In the Clutch artbook of Skylanders: SuperChargers, Cauldrone is revealed to be a scrapped core Magic Skylander, with a bouncy disposition.^[1] When they were made into an enemy, their pink and green eyes were replaced with malevolent black and red ones, and they no longer have their lid.
