Adam Cheplin is the 6-year-old son of Mrs. Cheplin and the younger brother of Dana Cheplin. He attends the Miller School with his sister and needs to be picked up at the bus stop at 3:15 p.m. sharp. Adam has a lisp and likes grape jelly the best. He is a chatterbox and it's hard to keep up a conversation with him because he does most of the talking. Moira is one of his friends.
