The pegomastax is a pick-pocketer, in order to tame have no sinomacrops, or any dinosaur on your shoulder, then, put berries in the last bar slot and walk to it slowly, and it’ll jump on your face and take all of those berries, then, put more berries in that same slot, then repeat.

It does two things: fast pick-pocketing, and regular pick-pocketing.

THE WHOLE TIME YOU WHERE TAMING HIM IT WAS PICK-POCKETING THE WHOLE TAME STEALING THE BERRIES!!!!!!
