Let "Kat", the talking kitty introduce young children to the fun of Hot Dots! This Hot Dots Jr. Pen talks, laughs, lights up with a green answer and a "you got it!" for correct answers, and lights up with a red light and an "incorrect" for wrong answers, allowing for independent discovery. Children simply press the pen down on the Hot Dots to receive instant feedback on their chosen answer. Requires 2 AAA batteries (not included) and measures 6" in length.
