Crystaline

Crystaline was a precious crystalline mineral mined by the Toad Empire, found only on Crystal. Under the supervision of Toadborg Crystal was mined by the Empire using enslaved beavers, who escaped with an storage tanker's worth of crystaline and they were set free by the crew of the Righteous Indignation.

Later, Frix and Frax successfully mined enough crystaline to "last an eon," but lost the shipment when they tried to ram the Righteous Indignation with their tanker and smashed into an asteroid. Along with the Toad Air Marshall, they were subsequently forced by KOMPLEX to mine a whole new shipment of crystaline all by themselves as punishment.
