Balloony is a generally kind character, but he won't take attitude from other characters, and can become irritable towards bossy teammates. Balloony has proven to be smart and good at problem-solving, similar to Tennis Ball. Balloony is also pretty brave. When deflated, he isn't capable of too much movement, let alone being able to even stand. Balloony can also be protective, as seen in "What Do You Think of Roleplay?", when he told Nickel not to stab Woody.
