Bloubert was an ooze that had coagulated and taken shape in the lands of Arche Terre. As a result, he developed a unique way of speaking...a blend of French and broken English. Bloubert possessed the ability to bring different liquids to the surface of his body depending on his emotional state. When threatened, his ooze became toxic and irritating to the touch. When happy, it produced tingling, pleasant secretions that were far more welcoming.

Bloubert longed to blend in with the local populace and make friends, though he also had a cheeky streak when it came to minerals, which he needed to maintain his solid form and continue growing. Despite his unusual nature, he meant well and was friendly, patient, and eager to connect with others.

However, his body could be unpredictable. His gelatinous form would often ripple, wobble, or spasm in response to sudden sounds, strong emotions, or unexpected sensations, sometimes making social interactions more complicated than he intended. Even so, Bloubert rarely let this discourage him, approaching the world with curiosity, kindness, and a good-humored outlook.
