This hatchling could hardly be considered cute.

Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it typically marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.

Mu bobi is a very soft and squishy bone marrow dragon because he is a new born hatchling. He mostly stays in the cave and plays with his older brother, Sairentochirashi. His brother knows better than to be too rough with him and they get along really well. Mu bobi is always looking for something to eat and bothering his adoptive father, Ketsueki no hone, for more food to eat. His Ketsueki loves to take care of him and he uses this to his advantage to get what ever he wants. He does greatly respect Ketsueki and would never to anything that would hurt his adoptive father's pride.

His name means defenseless.
