how do I paint on rubber?

I found this adorable rubber dragon in the bargain bin of my local toystore and would like to paint it to give it a costumized look.

Unfortunately the toy is made from a material i'm not to familiar with.
it's very stretch and it seems to me like it is made from supple rubber.
It's sort of reminds me of a dog toy.

so now I'm trying to find out what type of paint I can and can't use as I don't want it to start flaking.

I'don't mind if the toy becomes stiff. I'd will be more of a display item anyway.

Could I use spray paint? should I prime it? should i strip the current paint, and which solvent would be best that wouldn' destroy the toy.

Any help will be very much appreciated.

If it is indeed made up of rubber, then you can colour it with some pen colours, but it may get mixed up with the original colour
Don't deface poor Spyro. But if you must then use acrylic paints.

I didn't know it was Spyro (I never got into the games). Interesting.
I am definitely persuaded to keep the original scheme, but I do need to clean up the paint quite a bit. shody craftmanship n stuff.
