--------------------

1 - kdm7/roundhouse
Roundhouse (Design by crealol2)
The right-hand man of a princess We have never heard of, but can only assume is equally unsettling.

2 - kdm7/champ
Champ (Design by SmittyGrotsmeat)
She can control the mandibles on top of her head, often using them to break up fruits for her friends. The wings on her back seem to be vestigial, however.

3 - kdm7/comma
Comma (Design by puff)
They say she always knows exactly where to go, but recently she's been a bit lost around the Princedom.

4 - kdm7/kissy
Kissy (Design by SmittyGrotsmeat)
A spacefaring cousin who loves making friends. Took up work as a hero in the footsteps of her planet's savior.

5 - kdm7/muub
Muub (Design by Mira)
A distant cousin who spends all of his time online. It seems like he can't catch a break, everyone he meets there gets into some controversy...

6 - kdm7/pumprince
Pumprince (Design by @BandaiNamcoUS)
We're almost certain this is The Prince in a Halloween costume, but we'll play along for now.

7 - kdm7/dango
Dango (Design by c0reoftheearth)
They each claim to have different flavors, but they'll never let us taste. We're pretty sure the green one wouldn't mind.

8 - kdm7/otto
Otto (Design by Versillion)
This cousin is easily bored, yet very fun to be around. He enjoys activities that don’t require sitting.

9 - kdm7/bill
Bill (Design by Florpz)
A confusing looking individual who seems to think he blends in much more than he actually does. He'd ought to get a haircut.

10 - kdm7/lulu
Lulu (Design by Mira)
She thinks herself to be incredibly fashion-forward, but We've never seen her wear anything that wasn't on its way out.

11 - kdm7/penelope
Penelope (Design by Mira)
A cousin who constantly dreams up new ideas but never seems to muster the confidence to act on them. Seems bothered by Cosmi.

12 - kdm7/connie
Connie (Design by Bellhuko)
A silly, yet sweet cousin who’s great at making candies and confectionery. She wants to make the whole world happy.

13 - kdm7/quince
Quince (Design by LIMBO)
Someone who takes pride in lookng like a more royal version of The Prince. He's not actually a blood relative, but We are quite impressed by the similarities.

14 - kdm7/fuukina
Fuukina (Design by Velvet)
She tries her best to hold her head up high, sometimes with her hand. We heard her dream is for her band to become famous across the cosmos.

15 - kdm7/baub_bro
Baub Bro (Design by crealol2)
There's more of these? Is this squared-off look "in" right now? We are not a big fan of whatever trend this is.

16 - kdm7/cain
Cain (Design by crealol2)
This festive cousin loves the holidays! When he's not hanging off of a tree, at least.

17 - kdm7/neil
Neil (Design by SmittyGrotsmeat)
By the looks of it, this cousin has been dipped in a delicious batter and fried to perfection. We are unsure if this is reason for concern.

18 - kdm7/rince
Rince (Design by 86 Bottles)
This cousin aspires to be a true scoundrel, but so far his constant attempts to heckle The Prince have gone completely unnoticed.

19 - kdm7/zizi
Zizi (Design by LIMBO)
A Z-shaped second cousin who is surprisingly good at lifting things. She’s trying to make the world a better place for abnormally shaped cousins like her.

20 - kdm7/shinkansen
Shinkansen (Design by Chorus Kids)
This cousin can take you anywhere, for a small fee. Lately, they've been struggling with back problems.

21 - kdm7/kingser
Kingser (Design by puff)
Please get this away from us.

22 - kdm7/bluebelle
Bluebelle (Design by Robocami)
Thanks to advancements in technology, Bluebelle was born. She looks up to her mothers, even tending to mimic them.

23 - kdm7/harmony
Harmony (Design by Mira)
This cousin claims to have suddenly acquired the miraculous ability to listen to radio stations with only her mind. We have no idea if this is true.

24 - kdm7/earl
Earl (Design by Mira)
This cousin's greatest joy in life is exploring the lands and seas of planet earth. Now if only they didn't find themself lost every time they visit...

25 - kdm7/lucy
Lucy (Design by Mira)
This cousin proudly proclaims herself as a reprehensible evildoer who deserves to be feared by all. So far the worst anyone has witnessed is occasional jaywalking.

26 - kdm7/robin
Robin (Design by Florpz)
She views love as a shining light. She should do a bit less staring into the sun though…

27 - kdm7/lob
Lob (Design by crealol2)
This aquatic step-cousin's claws make it very difficult to hold fragile things. He's great at pinching, though.

28 - kdm7/bees
Bees (Design by puff)
A hardcore sophisticate who stays addicted to his work. Apparently he's Honey's distant relative, but that's still just a rumor.

29 - kdm7/buddy
Buddy (Design by Chuck)
A bouncy cousin who tends to attract insects. He loves to dance, but could use some lessons.

30 - kdm7/poppy
Poppy (Design by SmittyGrotsmeat)
A total dynamo that just can't be stopped once she gets going... for about a minute or so.

31 - kdm7/bella-paul
Bella & Paul (Design by Lilybell)
Two cousins who somehow got stuck together. We don't know how it happened, but they both seem fine with it.

32 - kdm7/pollie
Pollie (Design by LIMBO)
The princess of a magic country. She’s not as familiar with the cosmos as her brother, but she still remains just as sweet.

33 - kdm7/kaori
Kaori (Design by Mira)
A cousin who constantly chases trends in hopes of becoming "the coolest". Starts a lot of petty arguments with Tako.

34 - kdm7/selphi
Selphi (Design by SoduhParty)
A cousin with an interesting angle. She aspires to be a famous photographer, but can never seem to keep focused.

35 - kdm7/bon-bon
Princess Bon-Bon (Design by crealol2)
We are assuming this is the ruler of the strange, blocky characters that have been showing up. We think We've had enough.
