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, Tiny Vax, thanks to a potion that does that. Scanlan managed to go ahead and put in an Immovable Rod within its stomach, which held it up for a moment, before it decided to truly gain the advantage it needed to escape the circumstance, allowed it to tear through its body, as well as an arrow that was shot by you, towards her brother, in the hopes of, I don't know, being a symbol of hope?
DM: 22. Okay. Trinket (bear sniffs and growl) runs past here, but can only make 20 feet of its movement because he used the rest to get out of prone. However, strafes aside and begins reaching out and starts snapping, so you want to give Trinket--?
Player: He's going to attack him.
DM: Okay. As part of your attack action? Is that what you're doing?
Player: Yeah, I'm going to have Trinket do one of his attacks so I can move and run.
DM: As your bonus action on it? Okay, go for it. Have Trinket roll for an attack. With disadvantage because it is invisible.
Player: That doesn't count? I feel like it still counts, though. It's only 15.
DM: 15. Trinket slashes out in the air. With the obfuscation of the Stinking Cloud and the invisible dragon, Trinket's just getting mouthfuls of air.
