Catch-Me Krugg

Unlike its ancestor, which could move on both land and in water, the catch-me krugg is purely terrestrial. Its adaptations to land-based locomotion allows it to be very fast on land, with the trade-off that it swims only poorly. Indeed, it swims so poorly that falling in water will almost certainly doom it to being eaten by a predator. Though purely terrestrial, it still lives around riverbanks. This is only because it's fastest on wide, flat land, and as it relies on speed to defend itself, habitats that slow it down mean it's more likely to get eaten. Its ancestor used its third pair of legs as oars in water, and as mere support struts on land. As the catch-me krugg is entirely terrestrial, the third pair of legs are superfluous, to the point its movement speed isn't affected if the legs are removed. For this reason, it readily autotomizes (sheds) its hindmost legs if they are grabbed by a predator. Indeed, the legs are outstretched and covered in contrasting patterns to divert a predator's attention from the essential parts of the body. Predators include the toadtuga and the flunejaw.
