What I found in Lilou nose

Here is what I found today in Lilou's nose:

I found it curious she was putting her finger in her nose a lot.
Then, she grabbed my hand, and put my own finger in her nose. That was weird!
I touched something hard, and finally saw something pink deep inside.

After some minutes of struggle, I gently massaged the top of the nose downward, and it finally came out!
