How it all began... One day, high up on the magical mountain DINO ROCK, the crazy witch RUPULINA fully indulged in her secret passion: she cranked up the speakers to the max and played shrill solos on her black Flying-V electric guitar. The magical sounds of her instrument summoned a rumbling thunderstorm, and soon a lightning bolt struck the million-year-old mountain massif. Rupulina was astonished when a crack in the rock opened up and four dinosaurs and a dragon hatched from five colorful prehistoric eggs. MR. HEAVYSAURUS, MILLI PILLI, KOMPPI MOMPPI, MUFFI PUFFI, and the dragon RIFFI RAFFI learned from their adoptive mother to play and love Heavy Metal. Quickly, the dream of performing concerts and exciting even more people about Metal emerged. But Rupulina does not allow the Heavysauruses to show themselves to humans. Will they still manage to celebrate their first concert? A fun read for little and big Metalheads.
