If you're like me and can't stop playing until you've gotten every shell in the game, especially one as cool as the Skull shell, then check out how to get it in Another Crab's Treasure below.
Where to find the Skull Shell in Another Crab's Treasure
To find the Skull shell in Another Crab's Treasure, you must first reach Curd Village. If you've already gone through it and fought Heikea, you can just use yours Shellport Umami Skill and go to the Village Gates. However, if this is your first time going through it, I suggest ignoring as many enemies as you can until you reach the top of the hill.

You must kill the spider for it to drop the Skullshell. However, you will also have to fight against the hammer crab because it will keep attacking you. I suggest dealing with the hammer crab first where the sniper can't see you, or you might get impaled by a shish kabob when you least expect it.
Although the sniper isn't officially a boss, it definitely has a lot more health than the regular enemies and will hurt you. Try to achieve it fall out of sight so you have more space to work.
I suggest using a healing shell, like the Yoccult shell to give you enough time to defeat the crab. If it breaks, just run and grab one of the Cascadia is rolling who are in the area. If you already have it, I would suggest using the Adaptation of Mantis Punch do a lot of damage to the spider. Be careful, because it will also use melee attack you if you get too close.
One important thing is that you to take the shell as soon as the spider dies and drops it. Don't leave and come back for it, because it will be gone. Since this is a battle you can only have once, you will basically be locked into not getting a shell and completing the game 100%.
