This riddle was solved by the youngest student of the group.

Answer:

Lennie is like a child in that he constantly talks with slightly bad grammar, and exaggerates.

The rest of the school year passes grimly for Scout, who endures a curriculum that moves too slowly and leaves her constantly frustrated in class. After school one day, she passes the Radley Place and sees some tinfoil sticking out of a knothole in one of the Radleys’ oak trees. Scout reaches into the knothole and discovers two pieces of chewing gum. She chews both pieces and tells Jem about it. He panics and makes her spit it out. On the last day of school, however, they find two old “Indian-head” pennies hidden in the same knothole where Scout found the gum and decide to keep them.

Summer comes at last, school ends, and Dill returns to Maycomb. He, Scout, and Jem begin their games again. One of the first things they do is roll one another inside an old tire. On Scout’s turn, she rolls in front of the Radley steps, and Jem and Scout panic. However, this incident gives Jem the idea for their next game: they will play “Boo Radley.” As the summer passes, their game becomes more complicated, until they are acting out an entire Radley family melodrama. Eventually, however, Atticus catches them and asks if their game has anything to do with the Radleys. Jem lies, and Atticus goes back into the house. The kids wonder if it’s safe to play their game anymore.
