Danny Phantom (2004) : 2x11

Although Danny Phantom can perform extraordinary physical feats, Danny Fenton is still something of a weakling. For this reason, Dash is assigned as Danny's "fitness buddy" to help him prepare for the Presidential Fitness Test at school. When Skulker appears at FentonWorks on his usual hunt, Danny Phantom, Dash, and Skulker are accidentally hit with Jack's new "Fenton Crammer," which shrinks them all to a half-inch tall! Worse yet, Danny's ghost powers don't work so well in his tiny form. Now, Danny and Dash must rely on each other's brains and natural physical abilities to get to the FentonWorks Emergency Op-Center and reverse the shrink ray before Skulker and his brand new fully-powered ecto-skeleton catches up to them.
