I love my meeroos, if there is any new coats, I tend to have them. I don't care if their 10L or 10,000L; I will collect them all. But here is a few suggestions I have, seeing my own brother do animals of his own.

For one;
We have alot of new things teens and even adults are interested in.
So here is the coat ideas I have;

Twilight;
-Vampires; Maybe an all black meeroo with red tulips. And custom eyes like, "Vegiterrian" or "Blood drop". One can be the golden brown and the other pure red with black specks.
-Werewolves; Maybe a solid brownish red coat with small little claws. Also just random color eyes, mostly a whiteish blue or brown.

True Blood;
There are many mythical creatures in this HIT television series. They can be something crazy, with little fangs or what not. If you go as far as the witches, possibly on the "Ears" part of the meeroo, attach a witch hat. It would be adorable.

X-men;
Yep I said it, and I will again. People adore the old hit Marvel series. Including the new and up coming movies that has hit the world.
Do one solid blue with big feet/paws. Or do one with metal claws, or one with a solid white stripe through it.

The Hunger Games;
A new hit series, already taking over the twilight lovers. Possibly a red or black or even brown meeroo with the "MockingJay" symbol on its back. Its eyes can be any choice of course.

Those are just a few, but too me I would buy them at any cost.
