Yeah, love those old b-movies! I see by your image that Frunobulax is about to pounce upon the unsuspecting Dork from it's dark-alley lair... ...hey, I've had an idea how to convincingly increase the size of your monster towards the end on the film. The National Guard get called in, naturally to destroy the beast. They hit it with everything they have, but... you've got it... the depleated uranium shells just make Frunobulax grow larger and more powerful until he can stamp on those Army Jeeps. Then "our hero", if there is one, has to destroy the beast single-handed. LOL! H:)
