Cosmo and his pals Squiggz and Flutter are on a quest to earn their latest merit badges. Cosmo, feeling like he's just a brainiac with no athletic talent, stumbles upon the "bulging muscles" badge—and suddenly discovers unexpected strength and agility. As Cosmo begins to believe the badge is the source of his power, he risks his friendships and even challenges the neighborhood jock. That’s when Grandpa Lou steps in with the biblical story of Samson, who mistakenly thought his strength came from his long hair rather than from God. The parallel helps Cosmo realize that true strength comes from within—and from a higher source—not from external symbols.
