I love Sammy’s artful manipulation of these little shitrats. If she’d wanted to, I’m certain she could have had Jimi and Mocha turn on Nova for his little stunt. And honestly Nova’s accident was just as much a result of allowing young fluffies full reign of more than a safe room on their own, as his own inability to remember to empty his bowels on a regular basis. On the other hand, he’s shown now that he’s certainly creative enough to lie and be defiant to punishments, so Sammy does sort of have to come down on that hard, lest Nova speak the Forbidden Words and doom himself for all time.
Nobody is surprised at Mocha buying that Tuffy poops. Because fluffies are stupid and Mocha is a bit dim even by fluffy standards.
