Farm, and Dog with a Blog.
- According to Deadline, the reason behind Girl Meets World's cancellation was reportedly due to the ratings of the show declining, which happened to a few shows such as Shake It Up (which also ended on the third season) and I Didn't Do It, which ended on its second season.
- In Girl Meets Goodbye, there is a never before scene with Harley and Minkus giving advice to Cory and Topanga. According to Danny McNulty, who plays Harley, he reported Disney Channel had deleted his scene along with Minkus due to unknown reasons.
- GMW is the first show since I Didn't Do It to be cancelled, which ended on October 16th, 2015.
