@whitewolfone I didn't know that! But of course, Mappy Kids is a Japan-exclusive game since it was never released in the U.S, if you seen that one thing in-game... You'll realize why it wasn't released here. But back to the Meowkie names.. I think they just leave the Meowkies unnamed in official English media of Mappy.

Oh yeah, I forgot to mention in the previous comment that the two Meowkies wear no bandanas around their necks and only have blue fur on their neck (chest?)

The main 3 Mewkies were given individual names in Mappy Kids.
Edit: Just checked. The girl is Mew-Mew, the neck bandana wearing one is Mewta, and the other boy is Mewchi.

Let's see....they were Meowkies, Namcats, and The Big Bit all at once. Led by Goro of course.

Wished Namco gave official names for each Meowkie to tell which one's which.
I gave fan nicknames to the three main Meowkies seen in official Mappy artwork: Mickey, the first son who looks just like his father Goro. Mimi, the only known daughter of Goro and middle child. Mikey, the youngest Meowkie.

If anyone's curious why I referred them as Goro's children, I've read the Mappy-Land manual that the Meowkies are his kids. Where I got the idea of whose the first child and that, if you take a look at these from the character art manual:
...The Goro-looking Meowkie (Mickey) and the female Meowkie (Mimi) have no artwork of them crying just depicting the two kitties grumpy and sad.
