Main Street is an area on Astro-Knights Island. It is a medieval, run-down town. Mordred's House, the Planetarium, the Crop Circle Inn, the Secret Sanctum, and the Castle of Arturus can be accessed from here. The Golden Coin can be obtained by jumping into the fountain. Like the Main Street on Steamworks Island, this scene contains a vendor area featuring cards from the Poptropica Store.
