A day at the beach. Tom wants to lay in the sand, but his rest is disturbed by Jerry, who walks by to go fishing. Tom ends up falling off the end of the pier as he chases Jerry and lands underwater, where he encounters a mermaid whose top half looks just like Jerry. A chase, naturally, follows, all underwater. The mermouse, however, runs into a swordfish, and it begins chasing Tom, too, turning into mer-Jerry's ally, until it gets stuck in what looks like a telephone pole. The chase is next interrupted by an octopus, which grabs hold of Tom until Jerry yanks him free when we discover this is all a fever dream of Tom's, and Jerry has actually been performing artificial resuscitation.

Lovely animation and a nice locale make this one worth seeing.
21 January 2014 | by (Bradenton, Florida) – See all my reviews

It's very appropriate that this short was included on the disc for the Esther Williams film "Dangerous When Wet". This is because in this full-length film, Tom & Jerry appear in a fantasy sequence--swimming with Ms. Williams. So, seeing the pair frolicking about at the beach in "The Cat and the Mermouse" seems like a perfect extra for the disc.

As I mentioned above, Tom & Jerry are at the beach. Not surprisingly, they begin beating the crap out of each other. Soon, Tom falls into the sea and sees Jerry...or what he thinks is Jerry. Instead, it's a 'mermouse'--a mermaid version of a mouse. For much of the rest of the film, it's like a standard Tom & Jerry cartoon but underwater. And, like in their appearance in "Dangerous When Wet", Tom doesn't seem to have any trouble breathing under water!

Like any Tom & Jerry cartoon before they were ruined in the late 1950s (it's a long story but these later films were dreadful), the animation is top-notch--better than the Disney or Warner Brothers shorts. With wonderful backgrounds, great animations and lovely colors, it certainly looks great. As for the story, it's the usual but set in a very unusual locale--making it more enjoyable than an average film in the series. Not among their best, but quite good.
