That's one of the challenges that used to be a staple here, way before the Bingo Challenges. (I can't even remember years--definitely more than 5 years ago.) It gets its name from the mix of vanilla, chocolate, and strawberry ice creams in one carton. There are 3 inspiration layouts posted, and you scrap a layout by mixing features from all 3. For example, you might use the color scheme from the first, the photo placement from the second, and lots of paint and scatters from the third.
