New York City, also known as the Concrete Jungle, is one of the busiest cities in the world. Mya lives with her mom, Ms. Lisa, right in the middle of the city. Ms. Lisa runs Concrete Jungle Day Care. Every morning, Mason, AJ, Serenity, and Sarah's parents drop them off before they go to work. Mya loves that her mom has a day care because she gets to see her friends every day. They eat together, laugh together, and play together, but their favorite part of the day is naptime. Yes, naptime. You see, Mya has a teddy bear named Sammy. Sammy isn't just a regular bear—he's a magical bear, one that can bring your dreams to life, and when the Concrete Jungle Kids take a nap, they go on adventures. With Sammy, the Concrete Jungle Kids can go anywhere.
