Here is a possible concise summary:
In this video, MatPat explores what would have happened if he had chosen to cover Slenderman instead of FNAF back in 2014. He tries to calculate Slenderman's height, weight, and BMI using various sources and methods, only to find out that Slenderman is actually overweight and not slender at all. He then compares him to Link from Zelda, who is extremely underweight and more fitting for the title of Slenderman. He also promotes his new FNAF merch line, which features various items inspired by the game's characters and aesthetics. He ends the video with his signature catchphrase and thanks the viewers for watching.
