I suspect we would do better to find someone to walk us through a modified version. The problem would be finding that someone, who actually wants to do this with a 6- and 10-year-old.

(BTW here is one of DS6's monsters, transcribed as written:

"eyeball raider
Danger Value 6/10
eyeball raiders are uncommun. They live in pepole's eyes. When it is spearing time, they use their arm spears to spear your eyeballs. Eyeball raiders have very sensitave noses. the only way to kill eyeball raiders is by putting something tiny there."
