The Dreamstone (1990)

S4E4 Trouble with The Miners

Mr. Blossom's beloved plant starts to droop, prompting The Dreammaker to dispatch Rufus and Amberly to the opposite side of the lake in search of the "Grow Rock," which has the power to revive the ailing greenery. Meanwhile, in the Land of Nightmares, Viltheed faces a power outage, leaving the tower cold and dreary. Urpogor sends Sgt. Blob, Frizz, and Nug on a mission to retrieve "Firerock" from the nearby mountains to restore the heating. However, the Urpneys soon find themselves in a predicament with the miners in the Firerock mines, who are frustrated over unpaid wages for their last delivery to Zordrack's henchmen.
