Retro saturdays and tales of a fourth grade nothing

I read this book when I was in 4th grade because I liked reading and I was bored waiting for the library to get new goosebumps books. Despite me renting it frequently, I don't remember much about it. I draw a blank about what happens or things that happen in the story. The only thing I remember is the main character is a boy named peter and he has a little brother nick named fudge

I know this is the 1st book and it would lead to sequels such as fudge a mania and double fudge. Lately I been wanting to rent all the books from my local library to get deja vu and be all "oh yeah I remember" I think I'll do that next week
