Hello my children I am going to teach you something. The series of letters and numbers below the drawing of Monika is called "Base64". Now it may not look like it but these letters and numbers hide a secret poem, and it can be easily decoded with a website.

If there's something I've learned
It's that you shouldn't trust her club
With girls of cuts
And necks with ties
She holds some secrets
She holds some lies.

That's a secret poem that was easily decoded with the website https://www.base64decode.org/
You can also encode if you wish any message and mess with your friends.
