For the first part of the commercial, puppeteers operated a full-scale model of the robot, which was later replaced by a CG version. Occasionally, the two were combined. In the early live-action sequence the puppeteers' shadows and footsteps had to be removed from the autumn leaves but the robot's shadow retained.

To get the CG model to interact with the water, the boy was dressed in simple blue 'robot pyjamas' and asked to frolic about in the muddy puddle. The boy's image was then removed and a CG robot rotoscoped to match his movements. Finally, the splashing about was restored on top of a well-lit CG model. Excellent reference plates for every shot allowed the details to be matched with incredible precision.
