Lego WeDo additional (1)

I walked past a modelling shop that was closing down and noticed they had 20% off Lego. The stuff they stocked was limited but I came across set 8293 which had a battery box, a motor, lights, a switch and various gears and a clutch.
When I got it home I used some of the parts and WeDo to create the Hungry Alligator with glowing eyes.

However, I couldn't get the lights, motor and sensor to all work at the same time. Not enough power from the USB connection? A big disappointment but I need to play more.
