Worm

A small, curved, worm-like figure moves along a wavy line, traversing from the left trough to the right peak, then descending and reappearing on the left side of the frame. The figure repeatedly climbs the right hill, reaches its peak, and then descends, only to reappear on the left side of the wave, continuing the cycle. The setting is a plain, light-colored background with a simple, hand-drawn wavy line.
