Bouncy the Ball

I would imagine the animation style having a cute simple feel to it

For this role you will be making music for the entire series I would imagine the series having like a upbeat kid friendly music to match with the kid friendly tone the show is going for

A joyful and jolly ball that lives in the North Pole of Ballville and gives presents to all of the good boys and girls in Ballville on Christmas aside from that he also has his own Workshop in which him and his elves make toys 

 I would imagine Santa ball pretty much sounding like a typical Santa voice

A shy blueberry donut hole he is also extremely best friends with a Orange bouncy ball named Tony despite his shyness he can overcome his fears on occasion

 Despite being a male character I would imagine donut hole being voiced by a female actress actress I would largely imagine him having a high pitch shy somewhat raspy voice

Physics is the inventor in ballville he often makes inventions and sometimes even potions Ovc's little sister Haylee is also a huge fan of him

 I would imagine physics to have a male high pitched nerdy like voice 

Ovc's adoptive brother who one day hopes to be a superhero in ballville and often Daydreams of all himself being a superhero

I would imagine Milo having a high-pitched child voice

Ovc's adoptive sister who is a huge fan of Physics (who is a inventor in Ballville) inventions and often likes making inventions of her own someday when she grows up she also hopes to be a inventor just like him

I would imagine her voice to sound like a high-pitched female child voice

Ovc's friend from The Real World

I would imagine his voice having a joyful but also calm sounding voice

Annie is a childhood doll of Belle is that has a talking feature in the show when activated she would say one of the three phrases in the addition lines I would imagine her voice to be a cute high-pitched female voice

Bouncy is a cute kind energetic and friendly red bouncy ball he is also extremely caring to his best friends Belle and Ovc despite being a male character I would imagine him being voiced by a female and I would imagine his voice being a cute high-pitched energetic like voice kind of similar to that to a child's voice to match with Bouncy's cute and childish personality 

Belle is Bouncy and Ovc's friend and Bouncys girlfriend Belle is also Bouncy's oldest friend as the two have been friends ever since they first met on the first day of preschool I would imagine her having a cute high pitched joyful and happy voice sounding some what like the G4 Pinkie Pie form My Little Pony

Bizzy is Bouncy and Bouncer's baby sister despite being a baby she is capable of saying a couple of words and a few sentences as well I would imagine her voice having kind of just a basic female baby voice note the reason on why some of the words on the audition lines are misspelled is because those are intended to be the ways she pronounces words since she is still learning how to speak

A Purple goth ball that usually does not show that much emotion towards people or her friends she also has a crush on Ovc and once you get to know her she can be a really great friend I would imagine her voice sounding like a deep sounding but somewhat high-pitched goth female voice it was also kind of sound like a teen like voice

A butterfly that is best friends with Bouncy Belle and Ovc she usually visits ballville during the Spring and Summer but sometimes stays in Ballville during the Fall and Winter to spend time with her friends I would imagine her having a cute extremely joyful high-pitched female voice

The Sun is always seen in Ballville at daytime he is almost always extremely happy and is friends with almost everyone in Ballville he sometimes joins Bouncy and his friends on their Adventures when he gets the chance to he is also brothers with the Moon.

 I've always imagined to him having a extremely joyful and excited high-pitched voice

The Moon is the Sun's brother and is always seen in Ballville at night time unlike the Sun the Moon mostly has a more calm and quiet personality he often also has a habit of falling asleep. 

I've always thought that the Moon's voice would be mostly calm and quiet well sometimes also Whispering his words

Izzy is Belle's twin sister she is also the leader of the ball scouts team which she was a part of ever since she was a kid

I would imagine her voice to sound like a somewhat high pitched female voice
