 Among the many deviations, the sequence in the book where the Cat balances all sorts of objects while standing on a ball, only to overdo it and come crashing down, is left out.The closest equivalent is the fishbowl and bubbles sequences.Also differing is the role of Thing 1 and Thing 2; in the original book, they were simply things the Cat brought along to demonstrate fun, but in this special, they are commissioned to help find the cat's "moss-covered three-handled family gredunza".
