I actually found a box of the Blue Raspberry PopTarts promoting the Fantastic Four: First Steps movie a few weeks ago at the local Walmart's. I ate them last week and found the flavor is much stronger and sweeter than the Frosted Strawberry PopTarts. The front of the box features the Fantastic Four that includes Johnny Storm aka the Human Torch, Reed Richards aka Mister Fantastic, Ben Grimm aka the Thing and Susan Storm aka the Invisible Woman.
The back of the box features five of the eight different images on the PopTarts. I finally got one with the Invisible Woman on it. Unfortunately, the images were still blurry.
Warning: You may have problems with the blue dye used in the Blue Raspberry PopTarts several hours later (if you know what I mean, then you know). I had problems after the first two but not with the rest of the package.
