Note:

This inventory is based on a later copy of the set. Sets from earlier production runs most likely came with parts in light gray and dark gray instead of light bluish gray and dark bluish gray. Furthermore, some parts (especially technic axles and pins) might have had completely different colors. The activity cards included with this set are the same as the ones included with set 9725-1. However, the minifigure parts were updated for this newer version of the set. As such, there are no instructions showing how the remaining three minifigures should be assembled from the 12 minifigure parts listed in the Regular Items: Parts section.
