Scroll Secrets Failing To Work?

[MegaLobsterFace]

I'm trying to unlock the secrets via the scroll hints, but following the instructions seemingly does nothing?

The first hint, to get the skull and the regen heart items from level 1 and then "follow a trail," just completely baffles me. I get the items and no special trail spawns or appears. Nothing on the map indicates a clue and nothing in the world around me changes. I tried finding paths from the default grid, just the normal dirt ones, from both the skull and the heart, followed *those* in random directions for 5 or so minutes, and nothing happened still.

Then I tried the "adverse fates" puzzle after looking up the solution. I read that you need to walk southwest until the map runs out and find some glitching textures.
I ran in the same direction without even stopping to grind for *20 minutes* and nothing happened. No textures, no changes, no jingle. At this point I'm just assuming either I'm completely misunderstanding the way these secrets work in and of themselves, or my game is just bugged and not progressing, because even after *hours* I have not made any reasonable headway with any of them.

Except the "be a good boy in x level" one, which also only triggered once I'd attempted it three times with no luck. Are the unlocks actually just... random? Do I need to do these tasks over and over again until the RNG gives them to me? I really don't want to resort to the cheat codes, because that just defeats the purpose for me.

For the first one, you'll know you're on the right track when pies start spawning on the ground.

For the second one, it shouldn't take 20 min, though it is quite a walk. You should probably wait until you have Red Death unlocked before trying that one just because of how fast he is.

For Marrabio, the one in Mad Forest do you even have the Yellow Sign? You need that BEFORE the pies will drop. Same with Minnah, the one in Dairy Plant.

For the first one, there are only two conditions (besides picking up the items) according to the wiki: "Collect 100 Floor Chickens over the course of playing this game; you can get the hundreth Chicken in this run. Obtain the Yellow Sign." Maybe you haven't obtained the Sign?

For the second one, you actually did it wrong if you were able to walk for 20 minutes. As per the wiki: "The player must enter Green Acres with Hyper Mode and Hurry Mode enabled. After heading south 18 tilesets and west 18 tilesets, the area's appearance will change drastically." Hurry mode doubles the time speed, so it would end at 15 minutes. This one also requires the Sign, so if that was the issue with the first one, this wouldn't have worked regardless.

For the third one, it just requires you to 'heal' a certain amount in that stage using the Dusting. Perhaps you didn't walk around enough to hit the plants enough until the third time. None of the challenges are random, other than potentially getting the weapons required.
