Home is Wally Darling's sentient house, Home speaks in onomatopoeias (creaks, bangs, knocks and squeaks) and in order to communicate with him is only through morse code language, Each sound he makes is basically a symbol in that language. He uses his windows to wave and uses his eyes to indicate what emotion he is feeling (sad, happy, angry, etc.) , Wally is a good friend of him despite Wally lives inside him, they enjoy their company and is always there for him when he's down

Pooky is the most intelligent and appears to be the most emotional of the Imaginary Friends. He speaks in an almost poetic manner. Though Pooky's exact background is unknown, one thing that is known is Pooky is the imaginary friend of Annabelle Walker. He is said to used to look different before Annabelle went to the Hathmoore Children's Asylum, possibly having a name more fitting of his appearance. Pooky has brown cardboard wings, though it is unknown if he can fly.

Marco is one of the main antagonists in The Friends We Left Behind, he speaks in stereotypical pirate lingo exclusively. He appears to like water as well, since he spends most of his time in bathtubs filled with water. Marco has a gruff personality and seems completely unintimidated by Polo, even going as far as to threaten him with his hooks. Marco also has an affinity for rubber ducks

The Orange Imaginary Friend from IFA/TFWLB

Polo is one of the main antagonists in The Friends We Left Behind. He seems to dislike the idea of playing "Marco Polo" with Marco because he thinks its "too easy" which is ironic because the game is literally their names put together. Polo appears to have a low and thick voice with an Italian accent. His behaviour is similar to a Italian stage actor, he also likes to fan himself allot for some reason. Such a drama queen

Drooper is a lion who plays the bass and often sings. When he speaks he sort of has a southern-like accent to it. He is the ultra-hip hippie of the Splits who is always on, always cool, and always trying to con someone, he can also be a bit of a prankster allot. Although he treats the facilitator (You) the opposite, he's nice to them and often hides his prank schemes from them. Drooper can act like a cat sometimes but he doesn't show to anyone. (this is real I'm his right ear /j)

I am a very old clocktower in Jollitown but not as old as my dear friend Pipoy! I like to wake people up in the moring with my special alarm *DINGG DANGG DONGG*  I can also time travel from the past to the future! but dear me I am already old so sometimes I time travel by accident! I do sincerely apologize to my dear friends who have to experience that... I may look friendly but this old clock can talk back! People call me sassy and I know it ✨

Jollitown's favorite clocktower!

Shopkeeper is the owner of the "generic grocery store" that Cashier works. He is Cashier's employer and adoptive father, he's around in his 40s and only a tad bit taller than Cash(He's short AND old pick a struggle my guy /j)

They're chill and laid back, a humorous guy even likes to smile and laugh all the time to keep everyone and himself happy. Although he takes his job very seriously so if something happened to the store then your done for.
