Blubbug

The Blubbug is a round insectoid creature that moves by spinning forward on its small brown legs. Blubbugs are generally docile, roaming a set area while ignoring leaders and Pikmin, but some will run towards those they see in an attempt to bounce them away with their thick layer of fat. Pikmin can be thrown at one to push it away, either for safety, or to place it somewhere where it can be jumped on top of to reach higher terrain.

In Pikmin: Dual Worlds
The Bulbous Blubbug is a species of bloather in Pikmin: Dual Worlds that bounces essentially any object that isn't part of the environment around by either running up to the target, performing a small hop, and sliding across the icy ground towards its target or simply sliding into them at high speed while spinning and standing on the ends of its feet. If it falls from a high place it will merely continue sliding.
