Hidden Stair and the Magic Carpet (Secrets of Droon - 1)

Underneath the steps leading to Eric's basement is a hidden storage space. It's dusty and old, nothing special at all, but when Eric, Julie and Neal, all huddle inside that gray room together, something unbelievable happens. A glittering light and then a rainbow-colored staircase appear and as the kids take their very first step down into the mysterious land of Droon, they know that only magic and adventure can await them.
