Its not a Time Traveling Alligator

Chapter four of to kill a mocking bird was a mysterious one. Scout finds some gum in a knothole outside the Radley place. At first Scout and Jem think that it might be an adults hiding place, but they soon disregard that idea because they believe that only a child would have a hiding place for their things. They eventually find a ring case with two pennies from the early 1900s. . This is mysterious as we don't know who the person who keeps leaving stuff in the knothole is. Who could it be? Boo radley himself trying to lure the children in so that he can eat them for dinner. A squirrel just collecting shiny and mysterious things and shoving them into a knothole. Could it be a time traveling alligator stuck in the void that is the great depression. Maybe he like chewing gum with all his teeth and the pennies are the key to him escaping the void and returning to his home world. I can say with certainty that it is not an alligator, but most likely is Boo. I think that boo is putting gifts in that knothole for Scout and Jem. Boo probably saw that Jem and Scout were brave enough to come by his house so he rewarded them. He could also be putting visible things in the knothole because he wants to see how the children react to the gifts that he gives them. If you base the theory on the rumors about boo then he is probably trying to lure them in. He is trying to take them in and end them like the psychopath that he is. However, my biggest theory is that the knothole and its contents have some connection to boo and his real life. Through the objects and Jem and Scout finding them we will eventually see boo and find out who he truly is.
