GI JOE Whale and APC.
ASP Guns
Dollar store Hovercraft engines.
Unknown parts.
The Cobra Leviathan was my biggest project of 2019. It took a ton of scratch building to get the top how I wanted it. Figures can stand in the top part and then it steps down into the inside. I used two dollar store Hovercrafts for the engines and ASP guns on the sides and a whole bunch of unknown smaller pieces and an missile launcher. My favorite of this is the top comes off and you can have a wheeled version of this as well.
