Bronkoo isn't very adept at combat, which can be bad, since it is a carnivore. Bronkoos are capable of dealing a moderate bite and charging at their enemies, stunning them. Bronkoos are also capable of running, if they need to chase or escape fights.
At socializing, Bronkoos can do unimpressive songs and dances. In the transition Creature Creator-Spore, Bronkoo wasn't changed significally, unlike some other creatures.
