Clock Tower

thumb|300px|right The Clock Tower is one of the activities in JumpStart Adventures 4th Grade: Haunted Island.

Inside the island's clock tower, the user helps a hunchback named Semimoto (a play on "Quasimodo") play various pieces of music on an old keyboard which is installed into the main piano. When the user is at Level 1 of the game, Semimoto starts playing in the Treble Clef mode which makes the piano produce organ sounds heard at high pitches. The user moves Semi's hand over to the correct key wthe mouse, indicated by a bat flying over a blank music staff, & presses it. If the key is correct, the bat will fly away. If the key is incorrect, a skull will appear to show where the key was pressed. A fart noise is heard everytime the user presses an incorrect key while moving Semimoto's hand. If the user misses three times, a new round will begin. Three melodies must be played to complete the game.

On Level 2, Semimoto's dad, Francis, plays in Bass Clef mode which makes the instrument produce piano sounds at low pitches; the user does the same thing. On Level 3, Semimoto & Francis begin to play together as part of accompanying each other. The user does this by moving the father & son hunchbacks' hands left & right one at a time with the mouse.
