Infectious disease squeeze-balls, full of buboes

The coolest gross-out toy under our tree this year is the $5 infectious disease ball, a squeeze-ball wrapped in mesh that erupts into disquieting, vividly colored buboes when you squeeze it.

It comes in bubonic plague blue, smallpox green, zombie virus orange, and cooties red. Perfect for the trypophobe in your household. They're especially fun to step on.
