RGB-LED with 6 legs? Answered

As far as I know, RGB-LEDs have 4 legs: 1 common cathode and 3 seperate anodes (or vice versa). Santa Claus has left me a RGB LED with 6 pins. Now I'm confused and he has left the country! Can anyone help and explain this to me?

Three cathodes, three anodes?

Basically, three separate LEDs in one enclosure.

How could I be so dumb to oversee this?
Thanks!

BTW You don't have to answer the above question! ;-)

Sometimes there are 6 pins for mechanical stability, and 3 of them are already connected common anode or cathode. Test it with a resistor-battery circuit to see!

Guys, for your information, the reality appears to be slightly more complicated:

1 anode Red
2 anodes Blue
1 anode Green
2 common cathodes

I discovered the pin configuration but how do you need to connect these to 3 analog pins of a arduino board?
