Samurai Apes Runestone?

[toxicpixie]

Samurai Pizza Cats, awesome. Fond, fond memories. Although everyone thought I'd made them up/imagined them as I must have been the only person I knew to have watched it on UK TV when it came up on Saturday mornings as a kid

They could have a Nurikabe.

"The nurikabe (ぬりかべ) is a Yōkai, or spirit, from Japanese folklore. It manifests as a wall that impedes or misdirects walking travelers at night. Trying to go around is futile as it extends itself forever. Knocking on the lower left part of the wall makes it disappear.[1] It has been suggested that the legend was created to explain travellers losing their bearings on long journeys" - Wikipedia
