I don't know how to do a google search to get a/some sprite costume(s). Can someone please tell me a good search to try, and I've already tried pit 8-bit sprite.

“sprite sheets”

I remember in the past searching something along the lines of “8 Bit Sprite Sheet” and having some success. A sprite sheet includes different frames of a sprites appearance (think different costumes) that are normally forming an animation.

I could make you some… ;-)

I use this: http://opengameart.org for all my sprite needs.
