Chuggabug [Wacky Races, #8, Lazy Luke & Blubber Bear]
This one isn't great I know, but its for completionists sake.
Honestly, the Chuggabug isn't an easy one to do "right" as there is very little to it, and what there is too it, is the rickety, off angle aspect of it, which RC can't do all too well. I'll porbably revist the Chuggabug at a later date when my RP is back to a suitable level.
T4 plasma. Also surprisingly durable thanks to the Red Engine.
