Snurmpet is an amphibian like creature. It can both live on land and on water. It hunts it's food in the underwater using it's trumpet like snout to trap it's food. On land it prefers to dwell on caves or places that are damp, cold and dark. With this preference, they will find their partner or their family by giving off a trumpet like scream . This is why it's belly is round, so that can air can be trap and give off a trumpet scream loud enough to be heard in the dark.
