Upon entering the farm, you'll find a large pig pen. To progress, you need to open a gate. There's a lever on a platform above the pen. To reach it, you'll need to lure one of the pigs to a specific spot. Push the small wooden cart near the pen. The pigs will react to your presence. Guide a pig onto the cart, then push the cart under the platform. Use the pig as a stepping stone to jump onto the platform and pull the lever.
