A water bear trundles across a brightfield field of view: a plump, faintly segmented soft body — six smooth-min discs — lumbers along on eight stubby clawed legs driven through a metachronal gait, near legs stepping ahead of the darker far pair, the hindmost pair leaning backward like the real animal. A DIC-style directional relief and a translucent bluish body with a bright membrane rim, a food-filled gut and scattered storage cells sell the microscope look. It ambles on its own with a plodding "モタモタ" bob; move the pointer to lead it and lift its walk line, scroll to change the walk speed, press to curl into a cryptobiotic tun.
