The change to breakfast means it isn't possible to not fight the piranha as part of breakfast (and whatever other wanderers show up before it), even though my current setting is to Harvest Nothing.
The path gives some HP regen, and non-path sources of HP regen don't work. There's probably a good way of handling that, but nothing simple is coming to mind.
Some of the passive skills for this path unlock combat skills with the same name. That will probably be difficult to support properly (in all the little ways that matter to people) without handling skills with identical names. There have been a few cases of that in the past, but none of them...

Looks like that URL hasn't worked for years, because KoL changed. Checking outside of a script quickly shows that you need place.php?whichplace=rabbithole.
Drops Meat and Drops Items are for equipment that drops meat/items during combat, like KoL Con 13 snowglobe. I don't think there's anything that would be useful for the script you want.
You can use
string_modifier( $effect[morninja], "Modifiers" )
to see the modifier an effect gives. That gives a string. Doing more with it depends on what your goal is, probably.
