With the Super Learning Watch, you can always keep track of time. It features cool animations and the original voices of the PJ Masks. There are 9 PJ Masks watch faces, a stopwatch, and an alarm clock with 3 alarm tones. When the cuckoo clock function is activated, a sound will play every hour. It includes 4 pre-installed learning games covering numbers, counting, addition, and shapes. The menu is navigated using buttons on the side. When you open the lid, the PJ Masks melody plays. It requires a CR 2450 button cell (demo battery included). The battery compartment is child-safe and has an automatic shut-off feature. Demo batteries are included.
