It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, Tiny Vax, thanks to a potion that does that. you 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 Vex, towards her brother, in the hopes of, I don't know, being a symbol of hope?
DM: It may have less than one hit point, in which case, you're just going to turn right back into Scanlan.
Player: I think he's dead.
DM: Let's find out. It has two hit points!
Player: Oh god! Oh no, but wait, I took damage last round, too.
DM: That was before you transformed. It was at the top of your round.
Player: Hey, I'm still a snake! Well, I'm not going to try that any more. If I drop form, is that my whole round?
DM: No, you just let it go.
Player: I'm going to drop the snake. Snake was a try and fail.
DM: It was a good idea. Just not a very strong snake.
Player: I drop the snake, try to get that little bubble of air (gasps), and I'll fucking cast Bigby's Hand.
DM: Okay! So, using that little pocket of air, you bring your hand up, you do your quick somatic components, shouting the phrase, and Bigby's Hand appears and is currently being squished between some of the walls of the stomach.
Player: Can he move at all?
DM: Yeah!
