Rex has been taking culinary lessons, but all his foodstuffs are largely inedible. While Rex goes off to pursue his career of becoming a gourmet chef, Arthur and Bob decide to try and pass off Rex's foodstuffs as new age art sculptures.
Rex goes to Dr Dog, and returns home missing an ear. The gang returns to Dr Dog's to investigate, and find that the physician has now begun to shift his focus to genetic engineering.
Rex finds his birthday present that Bad Bob has been working on: a working rocket pack like his childhood hero's, "Rocket Raymond." Rex eagerly tries it out, and gets sent on quite an adventure into space.
Bob's eating is growing out of control. Rex suggests that Bob needs to watch what he eats and exercise, but Bob has a better plan: plastic surgery courtesy of Dr Dog.
