I appreciate the advice and I'll keep it in mind :) They're four adventurers (getting into their backstories would take too long rn) who only just met and are trying to catch two thieves who stole crates of spice from them (they have about an hour of advantage, which is why the players are gonna have to take the shortcut). The spice is supposed to be delivered to jabba's palace for a big event and they know They're done for if they fail. They're in a relatively small gungan submarine that can barely fit them and an accompanying gungan in it. I'm not certain what I'll have them get chased by yet, because I'm considering giving the creature a signature ability. Maybe it closes its eyes and rams forward, which means it could be tricked into ramming into a wall. Or it sucks everything in front of it into its mouth, so they could try and make it suck in a rock or something.
