It says You're Next in Unicorn blood!!
Me and my best friends younger sister named E (her name starts with E) came up with it to get back at some of our friends who were yelling at us for a game we could play with the snow. The game was capture the flag...

So we went and I dyed some water with food dye, trying to make it look like human blood. It didn't work and came out a kinda magenta color. So we called it Unicorn blood. We even came up with a story.

We had A and E lie down on the snow to create dead body imprints. We then squirted the "blood" around making it look like a crime scene. We used icicles as Unicorn horns and stabbed them in the ground as well as covering them with blood.

My best friend helped out too; she made footprints in the snow that are supposed to be "unicorn tracks".

Once we finished, A came up with a theory about Unicorns.

The theory is:

Unicorns are real. When they get to a certain age, they have to murder a human. Their horn snaps off when they murder the person. Then their Unicorn genes drip out of their coat until they aren't silver anymore and they have the coat of a regular horse. That's way there aren't any unicorns in the world and if there are, they've already turned into regular horses.
