Fire and Ice

S1, E7: To lure Jayce to his death, Saw Boss puts a marker in the shape of the root on an ice planet that is about to be destroyed by a volcano. Herc lands the Pride on the ice which is then nearly covered by an avalanche. The native people seek help from Jayce and everyone goes to work building an ice dam and storing up snow to drop into the volcano. Monster Minds attack, complicating things, but they end up helping the people when their lasers blast the dam which prevents the volcano from erupting when all the ice covers it up.
