In the episode, "Ducky Mountain High", when Scrooge and his nephews and Bubba are walking to Goldie's log cabin house, they are almost flattened by a giant rolling boulder. Just as the nephews say "Lookout uncle Scrooge!" two nephews are seen to be both colored blue (Dewey). Right after that, Bubba grabs a tree branch and "plays ball" as he hits the boulder toward a cave, traping the Beagle Boys who sent the rock.
