Thanks to all those for the solutions in this list! I got an even quicker faster way of getting this cheevo!
- Enter "The Well of Souls" on free play.
- Get to the snake room (where the snakes slide down from the wall) towards the end of the level. (Same place as everyone has been suggesting.)
- There are 3 places where the snakes fall out. Get to the one all the way at the end on the upper ledge on the upper right of the room. But stop near the left button (there are two buttons on the floor to open the stone wall) before you precede.
- Choose the character with the shovel (shovel has a wide hit box when you attack).
- Then walk towards the area where the snake will drop. (Towards the upper right of the room.)
- This is where the magic happens! As the snake falls out immediately hit it AND GO BACK UP TOWARDS THE RIGHT BUTTON ON THE FLOOR IMMEDIATELY (or run a small circle til the snake respawns). For some reason this will immediately respawn the snake to fall out again. Then rinse and repeat.
The trick is to HOLD UP ON YOUR LEFT ANALOG (or run a small circle til the snake respawns) while your hitting the snake with the shovel. In this scenario you get to have one or two snakes spawn every second instead of waiting for the snakes to fall out slowly one by one. If you are impatient like me or you just value your time more then I suggest you try it out.
Good luck and happy boosting!
