Danny Phantom Season 2 Episode 10

Secret Weapons

Skulker's on a looting spree, snatching up a number of seemingly unrelated items. Unfortunately, Danny's attempts to stop him are thwarted by the well-intentioned meddling of Danny's new sidekick: Jazz. However, Danny didn't ask for -- and doesn't want -- Jazz's help, and after a series of humiliating mishaps, Danny blows up at his sister. In response, Jazz runs away from home... to Vlad's castle in Wisconsin! But it's only a ruse. Jazz soon manages to break into Vlad's inner sanctum and discovers that he has been using Skulker to collect the items necessary to upgrade the Fenton's stolen Ecto-Skeleton. When Danny arrives at the castle, Vlad makes Jazz don the improved battle suit in a no-holds-barred fight against Danny Phantom!
