Pinecone Grove is a small town many miles north of Canterlot. Rusty Nails often buys building supplies from his friend's hardware store there. The drive there is usually simple and easy, but one day, an ongoing road construction project turns it into a nightmare. Therefore, Rusty and his nephew Donald Axeblade decide to take an alternative route to Pinecone Grove, one renowned for a steep and twisty section that climbs through a mountain range. It seems like a good idea at first, but they've greatly underestimated the difficulty of "The Treacherous Way."
