Generally am not a fan of the character of Baby Huey, a rather one-joke character and especially in his later Famous Studios cartoons annoying. When it comes to Famous Studios' cartoons, there is a general preference for the Popeye, Casper and even Herman and Katnip cartoons (although they all had not so great cartoons in their later years).
'One Quack Mind' is an okay cartoon of his, but it isn't great either (there are worse cartoons out there than any of the Baby Huey cartoons but to me while they are watchable enough for a one-time watch none of them are great) and Famous Studios have done much better. Have enjoyed a lot of their stuff actually, though they did go into significant decline in quality around the mid-50s.
The story is very predictable and is not particularly interesting until the interplay between Baby Huey and the fox in his baby sitter guise kicks in just before half way through. Here, regarding Baby Huey himself, there is less of the big heart and good intentions that made him tolerable in his debut cartoon 'Quack a Doodle Do' and even more of the stupidity and dim-wittedness, he is annoying here and to be honest found myself rooting for the fox, a more interesting and funnier character.
Animation quality here is inconsistent, sometimes it's beautifully detailed and vibrantly coloured but some of the drawings do lack finesse, parts look incomplete and rushed and the fox's design is very much variable. The dialogue is somewhat simplistic and forgettable at best.
However, Winston Sharples provides yet another outstanding music score, even in mediocre or worse cartoons Sharples' music was never among the flaws (if anything always one of the strengths or the best asset). Also love the lusciousness of the orchestration here and how characterful, haunting and whimsical the music was without going overboard in either, even better was how well it fitted in the cartoon and how it merged with the action.
Voice acting is good, Sid Raymond, Mae Questel and Jackson Beck excel in the types of roles they play here (the dimwit, the sweet woman figure and the villain) and are instantly recognisable, suiting their characters perfectly. The fox is an amusing and suitably crafty adversary, while although with limited screen time Baby Huey's mother is quite touching.
While not hilarious or amazing, the gags are still mostly very amusing and well-timed, not falling into repetitive or mean-spirited traps. The morbid but funny ending and the fox falling into the boiling bath meant for Baby Huey turning into a lobster particularly so, though the "indian" gag may raise an eyebrow or two.
In summary, not great but watchable but it is all dependent on how you rate Baby Huey as a character. 5/10 Bethany Cox
