Hey Arnold!

Two cartoon hands, one red and one blue, give a thumbs-up and then clasp hands before twisting into a spiral. The scene transitions to a blue-skinned character with a tall red mohawk, wearing a red jersey, who runs across the screen while holding a baseball, then leaps onto a tightrope. The character is then shown falling, followed by a white creature with a red eye and a red character with a blue mohawk, all against a plain yellow background.
