As promised here is the super special cheesy route for farming the frog for your very own zealot blade!
Step 1: clear mobs up until here
step 2: walk until you see this tree
step 3: walk up said tree until you clip the area circled
step 4: be flung into the air like so
step 5: clear rock dude and proceed to bridge
step 6: clear up to the barrier but DO NOT kill the bat boss
step 7: hug the corner like so before placing the seesaw
step 8: if done correctly seesaw should look as follows
step 9: click on seesaw and get off while strafing the opposite direction you think you're holding
step 10: barriers are really only a suggestion right?
step 11: proceed onto boss
step 12: Slowly die inside
then just attack the other frogs, die, and be ported back to the start.
