Ma Bagge and her company Growth Industries — in search of test subjects with the rare bloodtype "ABXYZ" — bribe Dr. Vindaloo into revealing his one patient with that blood type; Muriel Bagge. Ma's henchmen drag Muriel to their facility and Courage must once again rescue her.
- This is one of the few (if not the only) episode where Eustace gets a big amount of cash without/instead of getting hurt.
- The "Team Hair" part was cut on international airings of this episode.
- This is the only episode when Courage and Eustace get along (when Muriel was captured)
- You only see Muriel' s blood type, ABXYZ.
