In space, no one can hear you scream,

That's not, quite, right. There are lots of things to carry the vibrations of sound in wild space. You hear screams, all, the, time.

The PC's knowledge,

Some days ago you had set out from the Rock of Bral, the asteroid on which you make your home. Each of you knows the others, you had been making a good living joining the scavenger sorties into wildspace. You were hired by Captain Aldrich, an elvish treasure seeker with a reputation for going after the big scores. Bigger score, bigger risk, but bigger reward. You set out towards an asteroid field on the edge of wildspace, chasing rumours of some wrecked ancient spelljammers that held huge treasure.

Except something must have gone wrong, else you wouldn't be here. You are certainly no longer aboard the Nimbus.
As you attempt to open your eyes from a sleep you didn't think you needed, the bright light of a gas lantern is jarring at first.
The noise of this ship is different to your lamprey class, it sounds, bigger, more solid as it cuts through space, you must be far below deck, the ship must be huge, you can feel how close you are to the gravity plane. You have no idea how you got here, but you can't see the rest of your crew, as you look about you, you see that only the thri-kreen crew are in this room, obviously a brig, perhaps others are elsewhere, there was a compliment of 7 others aboard the Nimbus, but your head is groggy as you come to and see a locked door, a pale of water, a pale for other purposes, you see something approximating gruel in a 3rd vessel, and through a small slit in the door you see the back of one of your captors. Your belongings are not with you.

The goal is to survive, the party may kill all the clowns and claim the vessel(s), Steal one vessel while distracting their captors and escape, overpower their captors and force them to return the Lamprey, or any other myriad of ways this could be resolved.

This is the flagship of a space clown raiding party from clown space.

All the rest of the crew have been eaten /butchered for later the rest of your crew but did not eat you yet as they lack the crab crackers to open you up properly, and it wouldn't do to have you go off.

The party is aboard a space galleon, garishly decorated with bright carnival colours

There is a second ship 100 feet away to starboard, it is a Scorpionship that is also garishly decked out, it is towing the Lamprey class Nimbus behind it on a long cable. 200ft

Cable DC 10 to hit , break point of 20, or 100 HP.

The captain of the space clowns is called : Fun Land

The galleon is called The Harlequin

The Scorpion ship is called The Conniption

There are a dozen or so gadabout in the storage space of the forecastle

There are 2 children on the deck of the scorpion ship (actually clowns will electrify)

there are 4 guard below deck, in 2 groups of 2, https://www.dndbeyond.com/monsters/2821196-space-clown onboard the galleon 11 in total (one is the captain)

there are 6 clowns aboard the scorpion ship.

There is an ogre clown with a coiled up piece of cable for the ship cramped into Lamprey class ship https://www.dndbeyond.com/monsters/2560894-ogre-chain-brute and will be in the process of untying the captain who has betrayed the group.

Captain Aldrich will use the astral elf warrior stat block, https://www.dndbeyond.com/monsters/2821154-astral-elf-warrior

The denizens of a ship may release goon balloons towards the party if they are travelling through wild space away from the ship.

There is a murder comet flying in formation off the starboard of the Scorpion ship, it will not be visible from the Galleon.

Space whales will join the ship and tumble over it in formation and whale song before "swimming" off

4 tiny little chwinga astronauts, each mounted on 1 space guppy

A debilitated and very cranky looking Dragon turtle that lacks control of its direction, floating aimlessly into wild space.

Should the party escape with one of the ships, and clowns still control one of the others, they will give chase.

In campaign 2

This was played as a one-shot on 2022-11-23 (real date), "the crew of the Nimbus": level-4 insect-folk on a spelljamming galleon. It sits outside the campaign 2 storyline, but its events are canon in Eavaros.
