I "borrowed" the idea from another posted (sorry for not remembering who) and created this Siren out of a Energon Engergon Hotshot. I only used 1 Hotshot instead of the original poster's idea of combing parts from an Energon Hotshot and an Energon Energon Hotshot into one perfect bot. Instead, I just took mine apart and repainted. I googled Siren stickers and just copied and printed them onto labels (cheaper, but not as nice, as Reprolables)
