PepsiCo brand Mountain Dew is celebrating the permanent availability of Mountain Dew Throwback, which is sweetened with sugar, with a fully interactive online “Throwback Shack.” The website is designed to immerse consumers in the vintage Mountain Dew brand through a tour of the home of Willy, the 1960s animated Mountain Dew pitchman, the Purchase, N.Y.-based company says.

Mountain Dew first opened the virtual doors of the Throwback Shack in April and now the entire house is available to be toured online. In the interactive experience, Willy shares his favorite Mountain Dew collectibles with the brand’s fans as they tour through his home.

Throwback Shack users can enter to win prizes, such as retro-themed Mountain Dew-branded clothing, furniture, appliances and a 4-foot-tall statue of Willy, by “wanting” items as they go along. The updated tour features new prizes, including a flat screen TV, Mountain Dew pinball machine and a secret stash of Mountain Dew Revolution, a Mountain Dew flavor that is not currently available in stores. Fans can enter for their favorite prizes every day through Aug. 7.

While touring the Throwback Shack, fans also can listen to a retro music playlist on 8-tracks, upload their favorite Mountain Dew memories into an interactive scrapbook and explore Mountain Dew-inspired recipes, such as Mountain Dew pancakes, stir-fry and steak marinade.
