The school play was a hit, but Sara and Alex have lost the Mystical Pencil again. Stewart found it and used the pencil to design his science fair project — a working robot. The problem is, Stewart's robot stumbles upon the power of the pencil and decides to make himself a few friends. The helpful robot has drawn an evil robot as well and now the evil bot has created his own army. Can Alex, Sara, and Stewart defeat the robots and return the pencil to the museum before it is too late? Graphic Planet is an imprint of Magic Wagon, a division of ABDO Group. Grades 3-6.
