Pururumon is a Slime Digimon whose name is derived from the onomatopoeia for jiggling (ぷるぷる Purupuru?), and as such it wiggles as it moves. With a chubby body similar to silicon, it jiggles flabbily when it crawls forward. Both of its small fins are unexpectedly handy, but to be absolutely precise it is not yet able to fly. As it loves the smell of the sun, on days with good weather it lies sprawled on the lawn and smells the scent of grass with a sniff, immersing it in a good mood.
