Place the white chocolate in a large bowl and set aside.

Heat the milk in a large saucepan over medium high heat. Bring to a simmer but do not boil!

While the milk is heating up use an edible black marker to put dots on mini marshmallows to make eyeballs. Then use it to make 2 eyes and mouth on mini marshmallows to make mini ghosts. If you don't have an edible marker you can use melted chocolate instead.

Quickly pour the warm milk over top of the white chocolate and whisk until combined. Mix in the vanilla.

Divide the hot chocolate into 3 bowls. Dye one orange, one green, and one purple. Pour into mugs.

Spray with whipped cream and top with sprinkles, eye balls, and ghosts.

Top with whipped cream and sprinkles, "eyeballs", or "ghosts".
