The Jericho Serpent is a trumpet-like instrument, that when played creates a dark sound capable of freeing Vox from the Void of Silencia. However it has to be the right person playing it and that person is Satch, Vox's servant. The Jericho Serpent was silenced by Sugar Che and she dismantled it into three parts, scattering them across Los Bosmos in order to hide them so the Serpent could never be put back together and played again, which would release Satch. The Serpent features in the episode of the same name; The Jericho Serpent, in which Freefonix accidently free Satch again when they find all three pieces of the Serpent.
