I can waddle and swim whilst looking cute, but I cannot actually go noot noot. You might see me in a Desert or a zoo .

In the light, I give no fright. In the dark, I leave a mark. Tread with care, if you dare. But beware, as I don't care. Your foot has nothing to gain, as I will bring you great pain.

I represent the greatest song in the world, but I am not a great song, myself. People think of me as what I say I am.

I name a word that’s the same front to back, But I myself don’t follow that track. What am I?

I’m sweet and best when cold, but I can’t be eaten. I’m often associated with murder.
