S01E28 - Du violet et rien que du violet
Synopsis
Lumpy has made a wonderful birdhouse for his Uncle Grumpus, but is missing the purple paint needed to paint it his uncle's favorite color. When he and Roo find that Tigger doesn't have any either, they call the Super Sleuths for help. At first, they try alternate methods of decorating birdhouse purple. It seems, though, that they may already have the needed materials at hand.
