Freefonix - The Jericho Serpent

Children's animation about a teenage band that discover a magic note, much to the chagrin of the record company moguls. When Freefonix find a piece of an ancient trumpet named the Jericho Serpent, they are told by Sugar to find the other pieces so she can destroy them. After finding the other pieces, Freefonix accidentally assemble the horn and blow it, releasing Gavy, Vox's old henchman. Only, it's been so long that Gavy mistakes Mo for Vox! After realising his mistake, Gavy takes possession of the Serpent and finds the real Vox, forcing a showdown at ComaCo between Freefonix, Mantis, and Gavy before Gavy has a chance to free Vox.
