At school, when certain things happen, we respond.  When the whistle blows at recess -- we line up.  When the teacher says, "Class, Class" -- we respond with "Yes, Yes".  Both of those are examples of EVENTS.  In programming, events are an important part of the code.  They tell the computer what to do when something happens.  For example, when we press Start or Run -- the game begins.  When we click the Foo's belly, the code we created runs.  Can you think of other events in coding or in real life?
