Wheels also move and eyes light up - still need to solder the wires so it can work when the body is mounted on top. The wheels' movement is dependent on signal from the range-sensor. It's still kinda iffy.
The nose has a home-made capacitive sensor, made with a high resistor to accumulate and respond to current (the real capacitive sensor i got from the Prof. Galanter was too big, bulky to be able to fit it easily inside the robot's head. The robot doesn't like it's nose being touched. hides away when nose is touched.
Head bobs and eyes blink if the ears are rubbed (FSR's inside the ears).
