These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Good Bad Bugs: The fact that closing gates are stopped by any tiles Mario can interact with (including temporary ladders) results in an Easy Level Trick for at least one stage. Stage 2-3, to be exact.
Goddamned Bats: In the most literal sense, they can't even kill you by themselves but they are very annoying.
