Three...Two...One...Go! End of the countdown, it’s time to plant Underwood Springs’ flag on the Moon! In a cloud of smoke and sparks, Bigtooth’s rocket leaves the Earth’s orbit. Floating in space, No-No, Magaïveur and their friends barely have time to admire the landscapes before a meteor shower veers them off their initial course and sends them directly… to an unknown planet! Their meeting with Ribbit, a little green creature, will transform this space adventure into an interplanetary story of friendship.
