From Libs:

Have you guys seen this online yet? The first image is the real poster, the subsequent ones are the adaptations.

This is sad at first. A child lost their frog and drew a poster to
hang up in the neighborhood in case someone found it. Someone posted
it online
and now everyone is hiding the text in images and it’s become
a big gag, similar to the ‘All your base are belong to us‘ thing.
