Let the Adventures Begin

Your child picks a mission and Nani or Kian guides them through challenges, earning stars along the way.

Meet Your Child's Learning Guides

Every mission is guided by a ninja companion. Kids are never alone on their adventure.

Nani the pink ninja — enthusiastic encourager

Nani

The Encourager

Nani cheers your child on through every challenge. When a word is spelled right, she jumps for joy. She never gives up, and she makes sure your child doesn't either.

“Every mistake is just practice. You're getting better every time!”
Kian the blue ninja — curious problem-solver

Kian

The Problem-Solver

Kian appears when things get tricky. He pops in with a hint to help your child figure it out — because the goal is learning, not frustration.

“Hmm, let me think... I've got a clue for you!”
