Set in a forested area, the movie follows Kiki and Koko, two caterpillars who live with their butterfly mother, Katy, in Cherry tree. One day frustrated with their inability to fly Kiki and Koko run away from home looking for creature in the forest who can teach them. More often than not their search leads to characters who more often are interested in eating them than teaching them. Unbeknownst to Kiki and Koko, a quartet of aliens named W,X,Y, and Z have been watching them and have sent the shapeshifting X to capture them for food.
One of many foreign animated children's films released by now defunct home video distributor Just for Kids, Katy Kiki and Kok has been released under many alternate titles internationally from its native Mexico with its most notable US release titled Katy and the Caterpillar Kids. The movie is actually a sequel to Katy the Caterpillar which itself was an adaptation of a popular Mexican novelty song of the same name. While the movie is a sequel to Katy the Caterpillar it's not required for you to have seen it to understand the events of this movie (especially since a cliffnotes summary is told by Katy as a bedtime story to Kiki and Koko). With that said the movie is a rather standard children's adventure story that takes some rather odd turns.
The story structure of Katy and the Caterpillar Kids is very loose as its basically Kiki and Koko stumbling from one situation to another trying to learn to fly despite the fact they have no wings. Kiki and Koko are very bland characters with Kiki being a whiny wet blanket who complains and Koko being an impulsive trouble maker. The movie has them encounter varying degrees of strange scenarios such as a colony of ants ruled by a finicky queen, to bats and hawks who are intent on eating the two Caterpillars. The aliens in this movie don't even really factor into the plot until about 40% of the way through and even then most of what the aliens do is look through a viewing screen on their home planet providing color commentary on the movie through overly synthesized voices.
The movie also has a repetitive structure where Kiki and Koko runaway are found and then runaway again. This is because once the aliens do come into the plot no one believes Kiki and Koko about them, but it's a tenuous excuse at best that is easily resolved.
Katy and the Caterpillar Kids is a movie that will be strongly dependent on whether you grew up with it or not. The movie has decent animation that is vivid and dynamic but it's also got a rather shapeless plot. As a children's film it's perfectly fine, but I can't really go beyond that.
