This fuzzy robot chick-on-wheels joins a real penguin crew, and seems to fit right in with the other baby penguins. The stuffed-animal rover may look funny, but it helps scientists study penguins’ behavior without stressing them out (giant humans easily frighten the shy birds).

The penguins have accepted the robot into their circle, and TakePart reports that they’ve even tried to sing to it – and then looked disappointed when the robot didn’t reply.
