I imagine Bubble owning her own little aquarium in whatever home she moves into, perhaps one about the size of a small walk-in closet or shower stall, or maybe even a small swimming pool with a Plexiglas window if she ever had the finances to practice her underwater dancing and as some like to call it "underwater pantomime". Since she's mute, she can't pursue a hobby of singing like most of the rest of her species and especially her evolved forms, so instead she focuses on more visual forms of entertainment. She'll often make short, paid appearances at circuses, synchronized swimming shows, and even just take roles as background performers at concerts and ballrooms if the paycheck is good enough. Since in canon she mostly works for Team Missadventurers, they need all the extra cash they can get. X3
