I was looking for a micro controller with 3 ground pins and at least 8 other pins because I need to make an rgb led flash and fade between colors, preferably a smaller micro controller too.
Edit
I am so sorry I need a board like an aurduino not a micro controller I'm new to this

Why do you need more than one ground pin?
A single ground pin is sufficient. Simply connect it everywhere you need a common ground.
Why three ground pins?
The ATmega chips come in pretty small packages - 9x9 mm small enough for you?
People who don't know how to solder and don't own (or don't like - which is understandable) breadboards frequently complain about this. Even if you do know how to solder, it's annoying to make little splitters for the ground pins (though these little bits of prototyping board I sell are great for that!). I often wire up prototypes with dupont line instead of breadboard, and when I'm doing that, I often the board designers put more connection points for ground. Particularly annoying on the Uno, where they've got acres of unused board space.
But yeah - the correct solution is to connect the ground to everything you need to connect it to; you don't need additional ground pins on the board.
That said, there are a few boards (which I consider better designed) that break out more ground pins. I usually put 3-5 on my AVR breakout designs, and I've seen some with a ground pin right next to every IO pin; these are not mass market items though.
Oh - and there are three ground pins on the Uno - One of the ISP pins is ground too.
My Unos have 3 ground connectors.

Hi,
UNO 3gnds
Why not use one of these?
Tom... 
This version of the UNO I like has 21 ground pins... I hated that pin hassle too!
DISCLAIMER: Mentioned stuff from my own shop...
The barrel jack has a ground and the shell of the USB is a convenient ground when you're probing with a scope or meter.
