This will
require you to purchase the
supercharged shot from the weapon upgrades and
bait. (I would
suggest also getting the
bounce shot and
bounce bomb upgrades to make it easier.)
To use the supercharged shot you press
when fully loaded and then need to press
when the line enters the blue, and if you got the other upgrades for this then you do it again while still charged two more times, one purple which is a smaller area and quicker line, and lastly orange which is smaller and quicker once again but further back on the semi-circle.
Now go to
Landing Site - Outside the Javelin go through the cave and up the ice ledge, once at the opening go to the right and close to the sunken hole you can jump over this ice ledge to a grassy spot down below. Once here enter the cave with the crystals all around it and go straight to the end. Here is where 5 cave pufferbirds always spawn. Have your supercharge shot ready,
if using only the first or second charge throw 2 baits relatively close but with enough space for about half a bird in between. Wait until all are in the pile and shoot.
If using the third charge, I was able to get it without using bait everytime.
If you fail they do slowly come back or you can teleport to a different site and then back to landing site and they'll be back. I'll try and upload a video soon.
