Pet's Revenge (Edgar & Ellen)

Two Twins, One Eyeball, No Surrender

Pet has long endured the trickery of its mischievous masters, Edgar and Ellen, but no more! The one-eyed creature has newfound strength, willpower, and a plan that could tear the twins apart. Meanwhile, the Knightleighs have invaded the twins' house, and Edgar and Ellen are worried -- not until Ellen starts acting very oddly. She's tidying the house and taking baths. She's even accepted an invitation to a slumber party hosted by archrival Stephanie Knightleigh! Surely she's got a scheme up her (unusually clean) sleeve. Or has a hairy traitor managed to break up the devious duo for good?
