a man is standing next to a blue octopus.

Imagine a group of roommates, each from a different extraterrestrial species, sharing an apartment on Earth. You could have an octopus-like alien who's constantly changing colors, a humanoid with telekinetic abilities, a shapeshifter who struggles to maintain a human form, and a robot who's trying to understand human emotions. The story could explore their attempts to blend in with human society while dealing with their own unique quirks and cultural differences.
