Originated by Danny Van Eechaute of Belgium, this fast growing, non-registered cultivar is a sport of H. 'Hanjas Crazy Mouse'. It is a small size hosta about 9 inches tall with near-round, light green foliage. The leaves have thinner substance than H. 'Blue Mouse Ears' with a more pointed tip. In July, this cultivar bears clusters of pale purple flowers but is sterile so does not produce seeds.

One reference says that, "Hosta 'Skinny Mouse' grows faster and bigger than the rest of the mice."
