What clown movie is this?

I seen this movie. There was this clown, and he was molesting kids in a sewer. They made him look powerful and glorious. The clown had a power he could make even the kid with asthma trust him. but he was a monster. He wasnt a man at all. I think the main kids brother was abused by him too. Also, I remember something about him spying on the girl in the movie, she was in the bathroom having her first period or something, there was a lot of blood, and he was just laughing at her.

He terrorizes all the kids in town, gets em scared, then lures em into a sewer to molest them, leaving them scared for life. The kids in the movie.... I dont know... cant remember... I think after being abused, they grew up, and after hearing the clown came back, they were all so scared of the memories and shame of the abuse . One even killed himself naked in a bath tub.

and his name was pennyguy. I remember something else that he said. He was in the sewer and surprised the fattest boy and was like "KISS ME FATBOY". and they were holding hands and he snuck up on the children in the fog and just did creepy things (whispering in their ears and back massages). he held a little boys hand and he was breathing really hard.

Yeah and he had this room in the sewer where the light was so bright you cant see and he gets you. The bully in the movie gets molested and all u see is his face in the light while its happening, he just looks shocked and his hair turns white from his first experience with the clown
