Grisu: In The Volcano's Heart

SYNOPSIS

Fumé asks his son to watch over the water plant while he's away. Grisu accepts this mission and Stella comes along. But the young dragon accidently pulls the wrong lever, causing the water to heat too much. To cool it down, Grisu and Stella have to turn a wheel but they end up getting it unhinged. Fortunately Grisu and Stella manage to press a red button, which is a like a second line of defence. But their mishaps made the volcano shake and a boulder flattens a hot water hose. As Grisu tries to dislodge it, Fumé shows up in the plant unanounced, which makes Stella shout in surprise and startled Grisu burn two stalagmites holding the boulder.
