Elementary School Novel (?)

(I apologize if I mess up in anyway I'm new to this website and using it just to find this book!!)

I'm searching for a book where there was this cover that had a group of people and the main character (a teen boy I believe) was in the middle (i think with a camera or something in his hand it's too hard to remember). The story was mainly about a boy in middle school (I think). This is quite random but all I remember is that there was this scene where his younger sister vomits because she saw blood (or he mentioned it since it's first person) and she stayed home from home. The title includes his name in it. I read this book in elementary around sometime around 2016-2018 since it was in my teachers small library in the classroom.

(again i apologize if this is too confusing.)

Was it something from the Timmy Failure series?

>2 Hope_H: Unfortunately nope. I'm starting to remember a bit more but I think he had stuffed animals and his stuffed animals would fight (Unless I'm confusing it with another book). There wasn't any pictures inside the book I believe since it was a realistic fiction novel.
