Scratch

Though my answer might come off as lazy and unhelpful, it's probably the best one you'll get, with the lack of attention this forum receives (And an even greater lack of attention from Scratch's artists//thus my being here)

Google for one, I'd say. And if you find one, be wary of artists' rules with things like this- Giving credit where credit is due and just thanking them in the project notes or something. Though the probability of them finding out is slim it's just a general rule of thumb to credit artists or something
