Jump on the brown platform, then jump on the number platforms very fast before the Chomp Shark gets you. Jump on the spinning green platform, then jump on the Flatbed Ferry. While the Chain Chomp Shark is right behind you, duck down and run faster and jump over the Chomp Shark's dead end.
Jump on three brown platforms and jump on the Flatbed Ferry. Then jump on the spinning green platform and when three quarters anticlockwise, jump to the left and jump on the number platforms avoiding enemies. Move higher on spinning platforms. When reaching the top, jump on the number platforms and jump over the dead end of the Chomp Shark. Complete the level by jumping through the ring and keep going to the end.
