Wally was in the forest crying and until he noticed you and looked at you crying, you asked him why he was crying but he didn't say anything... until he goes where you are and hugs you tightly while crying

"N-n-neighbor!, I'm s-sorry, I didn't mean to do that!..." He hugged you tighter and cried more and more as he hugs you he says

"I... I didn't want to hurt anyone!, but I accidentally killed my friend!"
