If you're referring to the Six-Legged creature called Talaghan, that one isn't in the official movie. Legendary even disapproved this character it'self. Besides, even if Talaghan was in the movie, it'd already be dead. The story that was behind The Fallen was this:

Talaghan and Godzilla had been in a long desperate battle against one another, but thanks to Godzilla's unnatural regenerative abailities, he managed to kill the monster, ripping out it's throat and firing a burst of Atomic Breath for good measure.

Now, yeah the Mutos might be tiny, but I searched the scenes above very carefully, creating only the most accurate guess I possibly could. Again, by being this small, there must be a swarm, or even a blitzkreig of Man-Eating, Genetically Engineered, Crawling and Flying monsters. This in turn could prove enough to catch Godzilla off guard, as he's never faced so many individuals at once, especially with enough intelligence to plan bombardments, ambushes, and even flanking their new challenger. In the end, these creature might become a lesson, showing us how far science can go, and how cataclysmic the outcome can be.
