kit kat. I bought one pack of kit kat yesterday, but when i open it today, everything is gone, it is very smelly. I don't know what happened?

right. あなた brought a kit kat either when あなた bought it there was nothing in it または it has melted または somebody has eaten it over the night. but wait it as sealed when あなた 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 あなた think about it!!!!!!!

There's only one logical answer.... Kit Kat Squatters.

あなた 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 火災, 火 (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.

OBVIOUSLY!! DUH!

Ok. So あなた bought a Kit-Kat. Opened the package, and nothing was there and it was smelly? I don't know what to tell あなた but...didn't あなた notice there was nothing in there when あなた bought it?

maybe the kit-kat melted over night

it was melted
