teeny, TINY little red guys in the garden--what are they?

 
Found these under a brick in the garden. Literally RAN back to the house, grabbed camera, then RAN back to garden (as they seemed to be scattering quickly) to get a few shots.

This is not a quiz; it is a question.

(obviously wanna click on this and zoom in but this gives you size)

Anyone know what these pups are? I realize the shots are not the best. They had bright red, very round abdomens, like shiny balloons.

Did I mention they were TINY? They made pine needles look like giant logs.

Here's a detail of a photo for the best shot of their shape.

Not lookin' like mites, which is what I normally think when I see tiny tiny scarlet bugs.

Any wild guesses?
