C.O.P.S. - Season 1 - Eps 54: The Case of the Kidnapped Kangaroo Caper
Sundown had to go after Rock Krusher and Louie the Plumber, who not only kidnapped a famous Australian boxing kangaroo, but Whitney Morgan as well. The two crooks were holding them both prisoners at the Empire City Park in a forested area for ransom. Sundown was able to track them down, freeing Whitney and the kangaroo - who had a little joey tucked inside her pouch. With the help of this special marsupial, Sundown was able to take down Louie and Krusher and get the jump on their plans.

Synopsis
C.O.P.S. is an American animated television series released by DIC Entertainment and Celebrity Home Entertainment. This cartoon, which ran from 1988–1989, used the tag line: "Fighting crime in a future time, protecting Empire City from Big Boss and his gang of crooks". In 1993, the series was shown in reruns on CBS Saturday mornings as CyberCOPS, the name change due to the 1989 debut of the unrelated primetime reality show of the same name. The show was based on Hasbro's 1988 line of action figures called C.O.P.S 'N' Crooks.
