The Babs is a Maxis made creature, present in the final game. Notably, Babs's creator name is listed as "Jessica" instead of "Maxis", but they are still present in Maxis's Sporepedia.
Babs are adept fighters. They can attack with strong stunning charges, and then with powerful strikes. They can also bite, but not very well.
At socializing, they can only sing, and they aren't good at it. If they need to chase a prey or run away, they can sprint for large amouts of time. They also have a large spike in its tail which gives them more health than normal.
