Hard to beat a glow-in-the-dark top, and this one's a dandy. Untook one myself recently and spent quite a while poring over BrickLink for suitable glowing parts but somehow missed those horns. Worse yet, I had several of them laying around in my "I'll never use these" box.
Ah knowing I must face you in this battle fills me with dread and glee all at once. Even now I can feel the flagella butt-spanking me as we speak! Oh wait that's for my letter to Penth... uh, never mind. Forget that that last part. Great top, umm yeah that's it really!
