Hi, this one is my entry for Conceptart.org COW #110 Hyperactive.

On Planet Dilbert III, human colonists found perfect conditions to inhabit a fertile and uninhabited world. Also found some specimens of a creature they named Multipede tempusfugit, later known only as "What the...". They were rapidly adopted by humans as pets, due to their soft and multicolored coats and their calmness and docility. Unfortunately it was soon discovered about their mating habits too. Male multipedes had the hability to alter their movement through time. It could flow for them ten times slower than for anything else. It was an astounding evolutionary achievement, meant to reach as many females as possible in the short mating seasons.
What looked like the perfect pet changed suddenly to a hyperactive sexual frenzied creature moving in a dazzling blur of legs and tails creating havok all around him. After some frenetic weeks, humans freed the creatures, which by the way, were incredibly frustrated, as everything in their surroundings was soooo slow and boring...
