The story so far

A mascot, a meadow, and a tank to refill.

  1. Xplorer's tiny saucer crashing into an Earth meadow
    Chapter 1

    The Crash

    Xplorer's tiny saucer sputtered, coughed, and tumbled out of the sky — out of Knowledge Fuel for the very first time.

  2. Xplorer meeting a group of curious Earth kids
    Chapter 2

    First Meeting

    He woke up to a circle of curious Earth kids — boys and girls, big eyes, bigger questions. Somehow, instantly, they were friends.

  3. Earth kids learning with Xplorer, his ship glowing brighter
    Chapter 3

    Knowledge Fuel

    Every question they asked, every lesson they finished — a tiny spark of Knowledge Fuel glowed brighter inside Xplorer's ship.

  4. Xplorer and the kids exploring different learning worlds
    Chapter 4

    Worlds of Wonder

    Together they wandered worlds of Sciences, Languages, History, Coding and more — collecting fuel as they went.

  5. Xplorer's saucer flying home to planet Xplain
    Chapter 5

    Return to Xplain

    One day his tank will be full again. He'll wave goodbye, and rocket home to Xplain — because of you.
