The kids were getting rid of some transformers that were just beat to hell. Of course I had to come up with a project. The backpack is from a hero masher Megatron. A lego technic pin attaches the backpack right to the seeker 3 port exhaust. The tubing is a mystery. Maybe lego, maybe Megablocks. It was in a bulk lot of legos. It was 2 pieces but I used heat shrink to combine and bulk them up. The nozzle is from a "Walgreens" Shockwave. The handle to the nozzle is a cut down technic piece. The flame is hot glue sculpted around a technic pin that fits in the nozzle. Since I don't own Hotlinks, skywarp is my stand in. Enjoy!
