2009 was a year starting on a Monday, the 2009th year of the After Death (AD), the 9th year of the 3rd millennium, the 9th year of the 21st century, and the 9th year of the 2000's decade. This year comes after 2008 and before 2010.


In this year, the gang attended 4th grade.





The Butterscotch Effect. Barry had the possibility to meet his science hero, Dr. Fleming, but missed it because only high school kids could do it. To make Barry feel better for not meeting his hero before he dies, Cyd and Shelby go back to this year, and try to fix stuff, but then this causes the butterfly effect: when Barry met Dr. Fleming, he hurt him by saying Barry's theory were stupid, so he decided to leave science forever and start a band along with Naldo and Ray (the pizza guy). So Cyd and Shelby go back again to make things go how they were supposed to, only this time Cyd drops a pudding that distracts Naldo from meeting Barry, becoming his best friend, and so not making him become a jerk for not meeting his hero; so this re-causes the butterfly effect, and Barry becomes an alone guy who just wants to "destroy"

everybody by robots. At the end, Cyd and Shelby go back for the third time, make Barry and Naldo meet, and everything goes as supposed to.

We also find out Cyd had a crush on Naldo in this year, when Cyd and Shelby go de-aging in When Shelby Met Cyd.
