So what are your thoughts on the part in the trailer where you see that bomb wrapped up in slime?

The grim kaiju@ I think its like the fongus eggs in "Monsters" on those trees. But this time its a nest on a missle draining the missles radiation so the baby MUTO's in the eggs will survive tell they hatch. Without more radiation the hatchlings will keep dying. So that may be why they are fighting godzilla....to steal his nuclear energy for the survival of the MUTO race.

@Gojira2014- That is a very good speculation. I think that will probably be the case. Btw I love that name you gave me :) Thx

Maybe godzilla who craves nuclear energy from the bomb, ate it and maybe threw it up 

i believe that a bomb was launched at godzilla, and he caught it with his... mouth
