right. আপনি brought a kit kat either when আপনি bought it there was nothing in it অথবা it has melted অথবা somebody has eaten it over the night. but wait it as sealed when আপনি went to open it right? so it has just melted and stuck to the wrapper to create a smell. no ghost has eaten it. it is obvious if আপনি think about it!!!!!!!
There's only one logical answer.... Kit Kat Squatters.
আপনি see, in the night they have shrunk themselves -using magic- so they can squeeze into the tiniest holes in the wrapping.
They got cold through the night and lit a আগুন (You never know what they keep in their weeny rucky's) and that is how the kit kat melted. They all drowned in the OCEAN of melting chocolate. The smell is their filthy bodies decomposing.
