Did you miss me? My creative juices have been a bit stagnant since September. Then, out of the blue (pun intended), INSPIRATION! Power Functions Lights! In a robot! Genius!
I only had the one pair so I couldn't light him up like a Christmas tree like I wanted to. I'll add "buy more PF lights" to my to-do list. You'll be able to see the next one from space.
As for his backstory, Im not quite sure. If anything I'd say he's some kind of underwater construction bot.
