Titre original : The Case of the 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.
