It just seemed to… stare. So Derpy stared right back! But no matter how much she scrunched up her snout, the mechanical Applejack continued to stand, and stare. When Derpy blinked, it was gone.
The party went well, but there was something… off about the Applejack animatronic. Like it was nervous around Derpy. It was fine around Dinky, but Derpy… It was like the animatronic didn’t like her. And I’m not sure why—she’s the sweetest Pony in Ponyville!
