How to get "Exceptionally suspicious badge" in The Mad Murderer X

wer da rats: • Location of all 5 rats...
Having trouble finding it? Then y'all came to the right place.
I only made this tutorial because I do believe people will struggle on how to find it
Last time I checked only 6 users found it so far "17/07/2022".
hahahaehaehea the other badges are not hard people go figure.
Have a great day :)
