Presents
You put on the shellfish mask once per year and break into people's beach houses, leaving behind presents.
You're like beach santa, except you're real and you wear a mask made of shellfish.

The "presents" you leave? They are actually just zombies (ぞう). You leave zombies in people's houses.
Ooh hoo, it's me! the Shellfish Mask Man! I go to beach houses and leave presents where I can! The presents are not clothes, or anything good. I don't even care if you leave me some food. Try whipping some up, try cooking me peas, It matters not, I'll leave you zombies! Tee hee hee hee hee!
