marshmallow fluff in the carpet ...

yeah this is a nightmare lol. basically a container of marshmallow fluff got knocked over sometime during the kids sleepover yesterday. it sat there until today when i’m finding it. i got as much off the surface as possible but it is DEEP in there.

these are fairly new carpet floors and i have no idea where to begin ..😫 do you ladies have any tips at all to clean this or is it a lost cause..?! will anything loosen it up? freaking out here.

also not sure where to post
