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.
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.
