Barbie I Can Be Teacher Nikki Doll Playset: With these nurturing play sets, girls can explore the roles of a teacher. Barbie I Can Be Teacher comes with student Chelsea doll, who raises her left arm when the button in her back is pushed. Lessons can be written in chalk on the real blackboard (which flips to reveal a world map) and erased with the eraser that fits perfectly on Nikki doll's hand. The school themed piece-count also includes a student desk, scissors, lunchbox and glue bottle.
