A Super-Dee-Duper Day - S0.E73

While in the park, Ben shows Emma a brand new toy remote-controlled helicopter he got. While showing Emma how it works, Barney arrives. Shortly after, Ben's toy helicopter gets out of control and it breaks. Ben claims that there is nothing more fun than flying his toy helicopter. While thinking of fun things to do, Barney brings up the time they had a Sports Day in the park ("A Game for Everyone: A Sports Adventure"). Then they talk about their favorite games/toys they like to play, and Barney says that his favorite toy to play with is a ball, and tells the story of how many of the balls disappeared in the park ("To Catch a Thief: A Mystery Adventure"). In the end, Ben finds out there are more fun things to do than play with his toy helicopter.
