You keep eating and chewing and destroying until there are no ants.
You ate all of the ants.
Every single ant in the forest went into your mouth and you ate them.
Your nose is ant-free, but you offset the balance of the forest. The things who eat ants (besides you, obviously) become hungry and die and the things that ate them become hungry and die and the things that ate them become hungry and die and so on and so forth until you die, too, probably.
So you did not get any ants in your nose.
But you also probably destroyed the forest.
Good job on that. And good job on the no-ants-in-my-nose thing.
Really good job.
There are other adventures to try as well.
