My Yellow Nightwrite

This is my yellow nightwrite. My dad said I might get extra credit because it is "different". That is why I'm' doing this night-write on yellow paper. Because I am magic if I write on a green paper--I can turn invisible.
If I write on a blue paper I can stop time. If I write on a brown paper bats will come out of the ceiling and scare everyone around you. If I write on a black paper a one-foot tall black spider will appear in front of me, bare it's fangs and then disappear.
If I write on a red paper I will become good at everything. If I write on a gray paper I will get all the presents I want for Christmas. If I write on a purple paper I will get rich!
