Every great jack-o'-lantern starts with a blueprint. "Design. Build. Conquer." gives your little engineer full credit for their pumpkin-carving process — complete with a jack-o'-lantern schematic, tool kit, measuring tape, and a "Measure. Plan. Build. Repeat." checklist banner reading "From the minds that make it real." Because in this house, pumpkin carving is an engineering project.
