here's another aspect of the 13/73 slime theme: not only are there permeable slimes, but also the permeable slimes have different permeabilities!  
  
the explanation is very similar: in this cave with 13 slimes, each slime only gets 73 different rng values. also different slimes always get different 73 values, so each slime has its own 73 values. depending on how many "active" values there are among these 73 values, the slime can be more or less permeable. so in fact we have differently permeable slimes in the same cave! :d  
  
it's definitely possible to make crazy puzzles out of this as well! (in this cave, the solution is not unique. the magic wall time could be 4 seconds shorter.)

i meant to say "not only are there impermeable slimes..."

solution free!  
the mw time is 24 seconds, which is slightly more than two complete 73-frame-cycles (146 frames = 19.5 seconds).   
slime 2 is the most active one (4 active values per 73-cycle), so it swallows 8 ||| in about 10 seconds. the other slimes have 3, 2, 1 or 0 active values.   
slime 1 has only 3 active values, but it gets 8 ||| because ^ frees this slime first. other solutions are surely possible.
