Bizzare Book about Sasquatch

I remember when I was 6 or younger, There was a book about a boy being left alone in the woods because his mother was getting something (I don't remember what) and then suddenly, Bigfoot came out, in this book, they depicted him really obese and way bigger than usually seen. The child might have been stolen and the mother couldn't find him. The time period was probably 2011 - 2012 but my memory might be messed up

This book was... so odd and freaked me out. I cannot remember the title, and the pictures were realistic. We heard the book's story on audio, and there might have been a sequel to the book. 



this is a poorly drawn picture from my memory

I need to find this! Its so weird and strange, it intrigues me
