Seedy Sallys are a sub-species of Ukiki found in the Yoshi series. They're almost always found climbing vines, but there are some occasions that they'll go on the ground. Seedy Sallys throw Needlenoses. They appear in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Yoshi Touch & Go, Yoshi's Island DS, and Yoshi's New Island.
