Eddsworld and (Y/N) the "child" Eddsworld x Reader

Not good at descriptions, but here it goes... You had been living with Edd, Tom, Matt and Tord (yes Tord because I say so and it's my story... let's just say that Tord hadn't reveled his giant robot yet, and all four were still friends.) for a while now. You all seemed to know each other fairly well. And while recently for giggles and fun, you had put on Matt's purple sweater, it was kind of big on you and someone had commented that you looked like when a little kid would wear his/her parents shirt or something. You then got the idea to joke around and act like a kid, but while tripping over one of Matt's sweater sleeves, you hit your head on the wall and get knocked out. Once awoken, you seem to lose your memories and actually think you ARE a little kid. Some memories of the gang stayed, but others a complete blur. And now it's up to the four amigos to try and keep you safe and recover your memories.
