I agree with Shotta. There are lots of spike like irregularities to the edges of the blotches versus smoother edges in Simmiies. The dorsal blotches coalesce at the anterior end (and probably do the same toward the back end) and are oriented lengthways. While in Stimmies they tend to remain separate and be oriented saddle-like across the mid-line. It also has the 'butterfly' shaped blotch on the head that is very typical of Spotteds but not Stimmies.
