Catch scallops in the ocean and give them to Pascal to get DIY recipes.
How to Find Pascal
To find Pascal, you need to swim in the ocean. Try catching deep sea creatures, and when you catch a scallop, Pascal will appear.
How to get a Recipe
If you agree to give Pascal the scallop that you caught, he will take it and give you either a DIY recipe or a pearl in return. He can only appear once a day, so be sure to give him the scallop if you want a recipe or pearl. Otherwise you'll have to try again tomorrow.
