SONG OUT NOV 6, 2026
The second Secret Arcade cartridge, in black. Tap it to your phone and Blackberry Rhino opens: ride the rhino down the tunnel, jump the pits, slip the gaps, the song underneath it all.
This one is the key. The Blackberry Rhino game is gated, and the cart is how you get in: every cart carries its own code, on the chip and on the packing slip, and it unlocks the game to your account.
3D printed in Nashville and hand assembled. Limited run of 100. When the run is gone, it is gone.
