Famed French perfume master, Monsieur Stenchy, is holding a fashion show at the Youth Center. Skull is assigned to protect the top model, and accidentally makes things worse for her by dumping a bottle of the overwhelming fragrence on her. Inspired by this, the Louie Kaboom-controlled Machine Empire creates the Mr. Stenchy monster, a robotic skunk who aims to make the Zeo Rangers stink so bad that they won't be able to stand one another. Meanwhile, Billy tracks an undentified object approaching Earth from outer space, accompanied by a distress signal from Trey warning them of their planet being in danger!
