Harmony Treblecleff may be the daughter of an eccentric inventor, but she thought she led a pretty normal life. Normal, that is, until the grapes she grabbed from the kitchen suddenly came to life! Suddenly, Harmony is being attacked by a rogue Grape Tyrant from a distant planet (aptly named "Crazy") and his many tiny minions. Her only hope is the intervention of a new special breed of heroic grape warriors — ones that are SEEDLESS! Join Harmony as she teams up with her new alien grape pals — Funky, Pulse, Dash & Snap — as they ride jetpacks into the jungle, do battle with electric sabretooths, and reclaim their special robo-weapons called ROBOSTOMPS!
