Vypra collects an ancient powersource, the Starlight Crystals, with which to power a large laser cannon. Turns out, Kelsey's grandmother has one of them. But Granny, despite an athletic history, is now snobbish and stubborn, refusing to assist Lightspeed in baiting a trap to stop Vypra. But learning a lesson or two from Kelsey, Grandma Winslow rekindles her EXTREME past, and aids the Rangers in foiling the demon's plans.
