Wildberry Acai toaster pastry from Nature's Path

After the success with Nature's Path cherry pomegran pop tarts I came across and decided to try their wildberry acai. Never mind that acai is one of the last ingredient listed and I never could figure out what the 'wildberry' is/are. No 'wildberry' came up in my search and Nature's Path does not elaborate either. Still, it's all organic and more exotic than strawberry.

The twins were not crazy about it - I don't know if it's because of the flavor or the fact that they have already had pop-tarts. I will be sticking to the cherry pomegran while looking for other varieties.
