🎃 Hallowe'en Treasure Hunt 2023; hints for 4

Jack-o-lantern 4

In Mexico with
Sugar skulls and marigolds
Forebears are honored. (Lucy)

82 Petroglyph: #4: A big Halloween-esque celebration in Mexico is called el día de los muertos. What is that in English?

85 Petroglyph: #4: It's not a specific work, but the same kind of thing that clue #2 pointed to.

I typed in the Spanish words and that brought it up for me. It's not a book or a work.

128 Petroglyph: go to that tag page to receive a jack-o-lantern.

138 lorax: You don't need the English to get that one, but you do need the proper name for the day which omits 'los'.

145 Gryphon-kl :
#4 is a tag for the holiday described in the clue. Either the English or Spanish name should work .
