I accidentally swam close to a manatee in blue springs fl. Lemme tell you, biggest surprise ever. It flapped its tail and hit my thigh, blood bruise from hip to top of knee. Almost fucking drowned it was so painful. I cant see anyone hanging on to a manatee long enough to "carve" trump into the side of it. These fuckin things collect slime and shit like a sloth. I'm betting they just wiped the nasty shit on it off.
