Monsters started to come out of the ape monster's stomach as if it were only natural.

What's more, it was not just one or two or three...but hundreds of monsters came out of the ape monster's stomach.

They were all coming out as if it was only natural, and they were just walking out of it without any real disturbance to the forest.

However, as there were so many monsters coming out of the ape monster's stomach, the area around the ape monster soon got filled with monsters.

And since it got filled with monsters, the monsters began to move as they tried to make more space.

Right, they knew what to do in this situation as the area around the ape monster got filled. They knew that they needed to make space, and that is because...they knew that there would be more monsters coming out of the ape monster's stomach.

And it seems that was indeed the truth as all kinds of monsters started to get out of the ape monster's stomach.
