The deep sound of a mrrr (or mrr) can represent a sound of passion, love or happiness, like a sigh, in raptors, dragons and similar scaled creatures.

The sound can be long or short, and is usually sounded softly.

A mrrr could be seen as a more reptilian form of murr.

"Do you like my new dress?" "Mrrr."
"How are you today?" "Mrrr."
