Meet the Red Velvet Mite (Trombidiidae), at least I think it is -- there are thousands of different species.
It looks like a red russet potato with legs. Looking around at Google Images, I've seen a mite like this also identified as a chigger, but I suspect that it's a mistake. They are classified as arachnids, but they are not spiders.
I'm not going to go into a lot of detail about these mites. If you want to get a lot of factoids about them, I recommend What Are Mites? The Red Velvet Mite (Trombidiidae) that's part of Owlcation.com.
Interestingly, one Indian (the sub-continent) species of velvet mite (rombidium grandissimum) has some unusual medicinal properties. Check out Indian Viagra in Siddha Medicine also used for limb paralysis and to improve spermatogenesis
For something a little more whimsical, TheOatmeal goes into great depth on the subject of Red Velvet Mite Love. Enjoy!
