The movie's opening credits summarizes in illustrations of "A Story of a Little Chimney Sweep in the Year 1850". While the chimney sweeper is climbing:

  • The live-action cast members is portrayed in oval picture frames.
  • For the "animated sequences" credits, it shows the design of Tom ( Tommy Pender ), in his underwater design, and the design of the Otter.
The credits end at the top of the chimney, in which it cuts to the real chimney for the opening shot.

To start the closing credits, the movie's last live-action shot freezes into a illustration, turns into the same color scheme as the opening credits and the border frame fades in.
