What is IT? IT's alive, that's what it is! Turn IT on and try not to run when every one of its quivering filaments-and its eyes-start to move and squirm, seemingly motivated by a mysterious roiling, boiling, uncontrollable force within. IT's too cool. Black-light sensitive; approx. 4½"H x 5¼" diam. Takes 2 AA batteries (not included). For ages 6 and up. Style: Orange. Dimensions: Approx. 4½"H x 5¼" diam.
