Speak with Julieta in the -1 Depot. You may have to look away from the other NPC's but on the same floor north west.

Costs 2 Gold Nuggets to do a run, and advised to do it with a full group for better rewards. You receive your rewards at the end after killing the big jelly. The run has multiple traps and levers, and at times one of the members will have to hold a lever while the group crosses. Make sure you coordinate who is holding the lever and don't stop clicking it until everyone crosses and they are ready to hold the lever for you to cross. Good luck on your smuggling run! Also watch out for traps and false bridges.
