At least two possibilities

coolseemer:

The first is that the Death Star trash compactor had been used so rarely or that the station had been serviced so little that an ecosystem had begun to develop inside the trash compactor and who knows where else in the Death Star and a large tentacle beast had grown in this would be womb deep inside the most destructive weapon in the galaxy

The second is they just threw a tentacle monster in the trash

listen either finn is gonna get w/ rey (interracial couple in a prominent film franchise, still relatively uncommon in modern media) or finn is gonna get w/ rose (interracial couple consisting of two people of color in a prominent film franchise, even LESS common in modern media) or finn is gonna get w/ poe (interracial QUEER couple consisting of two men of color in a prominent film franchise, unquestionably groundbreaking) so like, no matter who finn winds up with romantically, it’s all good, it’s all important from a representation standpoint, u can all have ur ship wars but i am excited to see who our lord and savior finn chooses and will support him no matter what
