It was a cold evening in Canterlot, Twilight was researching a cure all cat allergy medicine. While twilight was researching the medicine, Applejack decided to pay her a visit. Twilight said to Applejack, "Oh Applejack, I didn't hear you come on, what are you doing here." Applejack said, "I was out taking my dog on a walk and the dog wanted to say hello." Twilight said, " I don't need help with anything really, I need to concentrate on this recipe I'm working on." Suddenly Winona started barking at something outside and Applejack was trying to figure out what it was. Suddenly, Applejack started letting out a sneeze and the sneeze knocked over the potion that twilight had recently perfected. Twilight asked Applejack, "Applejack are you okay did anything spill over". Applejack said, "I think you will have to check". Next thing you know, something unusual happened, Applejack started making barking sounds. Twilight said, "Applejack are you okay, I think one of my potions must have spilled on you, I just finished a potion that helps as a dog medicine but the side effect is it turns anything else into dogs." Applejack tried to respond but all she let out is another bark. Twilight said, "You know what applejack I'm taking you to Zecora". On the way to zecoras hut, Applejack started growing fur, it was unusual for her, she normally didn't like fur that much but she had fur now.
When they got to Zecoras hut, Twilight knocked on the door, she noticed that Zecora was home. Zecora asked Twilight what are you doing here. Twilight said, "sorry to bother you but I had an incident in my castle, one of my friends needs some help." Zecora then said, "I'll see what I can do, I need to see the one who needs help". Suddenly Applejack stepped forward towards the door alongside her dog Winona. Zecora said, "I'm sorry but it's hard for me to research two dogs if I don't know which dog is which." Twilight said to Zecora, "Listen my friend Applejack she had a potion spill on her and it turned her into a dog, we need some help." Zecora then saw the dog without a collar on and Twilight realized it was Applejack." Zecora said, "Good news there is a remedy, but the remedy requires a lot of hard discoveries and with accidents like what your friend had, after five days the dog side starts to take over so you only have five days to finish this adventure to turn applejack into her old self before she becomes a dog permanently with a slim chance of turning back, do you accept the quest." Twilight said, "Yes I accept this quest to turn applejack back to her former self." So Zecora sent the three of them back on their way.
