What's in a name? Meepos

Copyright on things that are common apart, but never before have been used together?

That is my little weird thing here... I have created these creatures called "Meepos" that are called so because they make sounds like "meep." They are round and furry with big eyes and come in a variety of bright colors. They live on the planet from my book "The Quest for the Emerald Leaf," the name of the planet is "Zemondraya."

My question is... there is apparently a character called "Meepo" who is a lizard-man of some sort.

Of course there are like a million things that look like a round thing with two big eyes.

And other creatures/characters say "meep."

But when you put it all together with the new things I've added... that's enough to make it different, right?
I hope so. So I'm putting this out there so that people will know what "Meepos" are, and so they know what they are not. "Meepos" are "rights reserved" by White Eye Books Co., est. 2009.
