disabled_by_defaultDue to increasing levels of AI scraping putting incredible strain on server resources but Cloudflare's under attack mode being a bit too heavy-handed to leave up 24/7, we're trying a new way to combat these attacks. By default, all traffic will be challenged but logged in users will bypass those challenges completely. We apologize for any inconvenience this may cause as it was never our intention to try to force registration and you certainly still don't have to - passing one of those challenges should keep you in the clear for a half-hour otherwise.

okay so like, the execution itself wasnt really that hard, but tryna come up with the idea was very difficult, i was looking through every underground background asset i could find online and non of em really felt right until i stumbled into this one site that has unused nsmb content and i was looking at old concept art of the underground theme and in that art was that one piller so i recreated it and then shifted things around and rescaled until i made this

also the semi solid with the skulls pushed this the longest in development cuz i wanted it to have the same skull as the bone goomba so i needed to finish the bones sheet
