Codename: Kids Next Door - Season 1 Episode 3

In "Operation: P.I.R.A.T.E. (Pirates Invade Respiratory And Treats Extracted)", a crew of candy-robbing pirates invades the KND's tree-house and make off with all its candy, including Numbuh 5's special stash, which Numbuh 5 refuses to give up, so they just take her with it. Now the other KND members have to save her and the candy, too. In "Operation: C.O.W.G.I.R.L. (Crazy Old Woman Goes Incredibly Really Loco)", in trying to outrun Mr. Wink and Mr. Fibb (from the show's pilot, "No P in the OOL"), the KND encounter an old woman named Lasso Lass, the sole remaining member of an original anti-adult league who thinks she is still a kid. Despite Numbuh 1's objections about her (he thinks you can't be with a anti-adult kids' league if you're not a kid), the other KND decide to let Lasso Lass help them recover a secret weapon of Wink and Fibb's called The Dome. Among other things, they learn that Wink and Fibb were once members of Lasso Lass' anti-adult league in their youths, but dropped out as they grew up.
