Is Barney expecting a sticker or some other reward?
Why is the child engaged? Is the child playing for the sake of play or for external reward? Is Barney expecting a “sticker” or some other reward? No, Barney just really likes the “whackwhack” sound the mallet makes on the dough and he also likes to watch the fat mound of dough become flatter and flatter as a result of his efforts.
