With “Genjin Show – Tobidase! VB Genjin” (原人Show ～とびだせ！VB原人～), another popular Hudson Soft series, “Bonk”, was once planned to make an appearance on the Nintendo Virtual Boy, but was cancelled in the concept stage due to the system’s poor sales.
The game was never officially announced, part of its design documents were released by former Hudson developer Norio Okubo on Twitter.
