Dear Santa,

Hey! There are so many toys that I want, but I just don’t have the money. I don’t care which toy I get as long as it’s one or the other, but not both!

Download the rar file

Extract the file we got two image

Extract the hidden files from 3.png

Use binwalk to find the hidden file

Binwalk told me there is png file but ididnt get it after using command:binwalk -e 3.png

So i use foremost -i 3.png
