Answer:
I smell like blue paint pours like green paint and I look like a red truck.
I grow up while growing down
I get wet when drying. I get dirty when wiping.
A dragons tooth in a mortals hand I kill I maim I divide the land.
I have memories but none of my own whatever's on my inside is what is shown. If I'm ever different it's because you changed me I feel like a decoration here for you to arrange me.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
