Mini Hiss Tank from Retaliation
Data Viper Missile Launchers
Dollar Tree turbines

I've bought a few sets of the Dollar Tree Final Faction weapon sets to add kibble to a variety of different items.

I hadn't figured out what to do with the turbines until they ended up in a fodder box of random parts and kibble next to a HISS without any treads. I dremeled here and there in order to get everything to mesh up right, and superglued the turbines to the base. I did some light dry brushing to make it look a bit more metallic.

I didn't want to keep the hole for the missile launcher and could not find anything to fill it with, until I happened upon some leftover soda cans that I had used in a Cousin Eddie custom years ago. I glued that in there and painted it black, finishing the deal.
