It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, She finds the pond from her vision after about 40 minutes of travel, identifies the footprints of the creature, and stealths after it. In a glade, after following the footprints for a while, you finds that the trail has gone cold.
DM: The creature glances over at Trinket behind, looks up at you in the tree and in a creepily humanoid way, wipes the edge of its jaw and then leaps off this tree.
Player: Trinket gets a swipe at him.
DM: Yes, he does. And then it leaps in your direction in the sky. (impact, roar) Arms out, jaw open. Make the attack for Trinket.
Player: I think he likes me, y'all. What is it, a bite attack or a claw attack? Does it matter?
DM: Whichever one you want.
Player: A bite attack, then. That is 12 plus nine. 21.
DM: That hits! Go ahead and roll damage for Trinket.
