"The Timber Wolves are a-howling!" shouts Granny Smith one night, banging pots and pans, and that means "The Zap Apples are coming!" The entire Apple Family's excited for the special harvest, and Apple Bloom volunteers to help Granny Smith produce the Zap Apple jam. But the process seems to require a lot of weird and nonsensical steps, and Diamond Tiara convinces Apple Bloom it's because Granny Smith's senile. Is Granny Smith really senile, or is there something more to her seemingly "silly ways"?
