no.
Coldstone only uses 2d sprites, so you don't need 3d sprites (we call 3d sprites 'models' btw).
A sprite is a serie of pictures, one for each part of a animation - usually ten for each movement. we call those parts of animation frames
For every single frame you need a picture of the sprite from every angle (4 or 6 angles).
You could make a 3d sprite, animate it, then take pics and use those. But that would cost you a lot of time if you have never done it before. I'm talking years to learn that, not just days.
Animation in 2d is easier, if you try it a few times you can get reasonable results, if you have the talent
The best way is to use sprites other people made and agreed to have you use for free.
If you read the forum, you'll find a few links to websites that have free sprites.
Also you can look for free sprites here in the addon files section.
Or, the most easy solution, just use the sprites you will get on the coldstone cd - they are not mario, but for a first game they are ok
