Continuity mistake: When a Cape Suzette National Bank agent threatens to repossess the Sea Duck, Baloo lifts him up from beneath the arms and starts pleading. In the next shot Baloo is holding the agent's outer arms instead. (00:15:00)
Continuity mistake: As Baloo argues with Rebecca over ownership of the Sea Duck, Kit reminds him of the treasure stashed at Louie's. In the background is a turntable near Baloo's armchair. Sometimes it has a cover that's propped up, but in other shots the cover is missing altogether. (This mistake can be seen in the original 1990 television movie premiere version. It has since been amended in later DVD pressings).
Polly Wants a Treasure - S1-E8
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
Vowel Play - S1-E9
Continuity mistake: When Baloo and Kit are discussing proper grammar, Rebecca walks into the room and tacks a poster on the wall using darts. One dart nearest the poster's right edge vanishes between shots.
