[TOMT] Late 90's/ Early 2000's TV show or movie of kid demanding his "marshmallow stick" over a radio when referring to a fire poker near a fireplace

Was some sort of thriller or horror tv episode or movie.

The scene was of a woman (alone I think) in a room with a fireplace. Over a walkie talkie or a radio or maybe even telepathy a young boy is demanding his "marshmallow stick" in reference to a fire poker near a fireplace the woman is in.

The woman is insisting that's not what it is but the kid just gets angrier in responses.

For some reason I think she was doing this against her will, like it's some kind of messed up scavenger hunt or she is looking for these items for the young boy under duress, either her safety is at risk or someone else's if she doesn't do what he says.
