Not the most elegant, but I didn't see anyone else's. I wanted to add Sludge to the G1 SDCC Ark drawer, and figured out a simple layout. I cut the foam where Slag was to accommodate Sludge, moved Slag under Grimlock and cut appropriately. I plugged Swoop's lances into his wings, and cut a slit where they were to accommodate his crossbow. Again, not the most elegant, but I thought I'd share anyway, as I figure others got this Sludge deco for this purpose too.:
