The WM ARC on Pristine Peaks.

The WM ARC, short for Washing Machine Advanced Rabbid Carrier, is a spaceship created by Beep-0, used by Mario's party throughout Mario + Rabbids Sparks of Hope. First appearing to save Mario, Beep-0, and Rabbid Peach from Cursa in the Darkmess Manta, it plays a key role in their quest across the galaxy to save the Sparks. The WM ARC comes with an onboard AI named JEANIE.

The ship can be further powered by Purified Darkmess Energy Crystals, allowing it to open warp tunnels for instant travel across the galaxy.
