Pencil: (A student 16 years old, but is going to be an adult later.) (Born 14th 2003 of August) (Sophom*ore and will become senior in the last episode) (Match is the same age as Pencil exactly too.)
Rocky: (Is 11 years old after BFDI was released but always sounds 6 years old since BFDI 14.) (He doesn't go to school because his age doesn't change up since BFDI 10.) (Rocky is a still-age human being in all the seasons of BFDI, and he shouldn't be a person.)
Tennis Ball: (12th Grade, but is never going to college at all after that) (Is born May 17, 2002 in bfb and bfdia) (Will be 18 in the furture but sounded 16 in the first bfb episode.)

Grassy: (Born in July 2008, 2009 or 2011) ( It sounds like a kid evry time the voice speaks in each episode of the season.)
Marker: (Older than Firey, so sophom*ore now, and junior in the final episode, or senior.) (2003-2002 could be how old he sounds.)
Lightning: (Sounds like a 12 year old or a 14 year old in the show, not 13 in fact.) (He's either born in 2005, 2006 or 2008)
Pie: (10th Grade) (Born July 23, 2003 or 2004) (15, 16 or 17 years old, but probably 16 now or 17 after.
Liy: (8th Grade and held back 3 times in a row) (Born in 2004 or 2003)
Loser: (47 years old and among one of the oldest contestants in the show.) (He doesn't have a school grade becuase he's older in the show and his birth is 1972 in October 14th. Loser would sound like an adult if it were a newer voice his than that of what he sounds in bfb, but he's older than that age and very old.) (Loser is going to be 50 if it were 2024.)
Teardrop: (10th Grade) (Should talk in 11th grade next year) (It sounds like it's 2005 or 2003 born for how she is, doesn't become younger than that.) (If Teardrop talks, it should happen next year.)

Naily: Is a small object, so 10 or 11 years old.)
Spongy: (37 years old, but is not getting older. than that.) (No school grade, also always in adult in season 1-4 for bfb and bfdi, and old man would be 35 or older for bfb season 1-season 4)
Pin: (9th Grade) (15 years old) (Born August 12, 2005)
Nickel: (8th Grade and a younger coin than Coiny) (Nickel is going to be born 1 year after Coiny in 2005.)
Pen: (10th Grade and not other grades at all.) (Because of 10th, he an older guy, so he's 2002 born or 2003.)
Pillow: (High School Freshman, 9th and 15 years old in the show, born in February 10, 2005,)
Roboty:(Never aged or never has a real age, he's a robot in bfb) (Firey doesn't allow him in
his class at all in the show)
Ruby: No more like a kid, ever since BFB 3, it's a senior or junior in high school) (17 or 18 years old) (2001, or late-2002,2003)
Saw: (High school every time voice cracks) (No mentioned grade between 9th & 12th grade at school)
Stapy: (4th or 5th high school year, he doesn't go to a real high school like every kid does at all) (He is born technically between 2006 and 2009) (His high school is like 5th grade-7th grade some times)
(Stapy can go to school with Firey Jr. altogether in a district)
Taco: (Born October 9, 2004) (12th Grade, because Taco is a super-smart contestant that beats haters out.)
TV doesn't have a real age becuase it's a television.
(49 years ago, commercials were invented to use ads to buy things and Yellow Face is that old.)
Coiny: (9th Grade) (Born September 9, 2004) (Always a freshman in hs.)
Puffball: (18 years old) (College) (Never going to be a kid except for fake rainbow sounding voice)
(Oldest season 2 newbie that sounds like a kid is Puffball, Puffball is not a kid and is an adult.)
Some Season 1s remaining in the bottom
Blocky
Eraser
Woody
Snowball
Flower
Golf Ball
Leafy
Match
Needle
Ice Cube
Four and X are last.
Eraser: (22 years old) (Graduated College last year) (Is like a high-grade highschooler to an adult now.)
(Erasernever is sounding like a kid at all)
Blocky: (11th in high school and a bully, he bullies 8th graders and10th graders too.) (And contestants that are in the younger years are very very very very very hurt by Blocky and his friends) (18 years old) (2001 or 2002 born)
Snowball: (4th year in College, becuase he's always a man in bfb and bfdi)(He's been an adult since the 9th bfdi episode)
Woody: (8th Grade) (13 years old) (Born in June 9, 2007) (Woody is sounding like a teenager now in bfb since episode 5.)
Woody is now in PACE Program at Forest Charter School) (That is where some of my friends go to now for school to learn)
Match: (Same year as Pencil.)
(Don't ask how old Match is according to my beliefs, okay, they are private)
Golf Ball: (Is Born in 2004 in April 7th) (She's a super-smart 10th grader that's always 16. Golf Ball doesn't have younger smarter kids than her) (The other smart people are older people in the show)
Ice Cube: (3rd Grade, she's going to sound like a young ice cube kid every day in the show) (There is no birth date just like Rocky.) (Speaking of which, they're the only one in the first show that sound below 10 years old.)
Needle: (12th Grade) (Voice is going to sound like a woman soon.) (Needle is a woman if she ages the exact amount of years from BFDIA to now.) (She is not just a regular student at school)
Leafy should be in the bottom because I hate her. Also, just let Flower and Leafy be the last two, okay, great.
Flower (the most mean in season 1, but Idon't hate.) (Is a freshman in high school and is not going to sound like a sophom*ore or older at all ever until the new season comes.) (Flower should stay 9th grade for an entire season though of BFB) (Hint: I'm not going to put Flower at age-gaining, since she's horrible in the first season a lot.)
Leafy (the worst contestant in BFDI) (Now, she's the youngest high schoolder in BFB, and skipped a grade in season 2.) (She's in 9th andshe's 13 and for how old she is when she is born in, it's 2006 in December.) (Don't think the same way of Leafy as I do for age, this means you think she's a young gsa student in school, GSA students are high schoolers that are very smart in high school) (Leafy is a beginner-of-age-student there, Firey can go to her school and then leave.) (Guess what: Firey now hates Leafy in 6th grade to sophom*ore high school yea and will never like her again after that happens again.) (Leafy deserves to be last on my age order.) (Firey is a good student and Leafy is a young student.)
There contestants are for how old they sound truely from BFDI to BFB season 4.
Here are the ages for the two hosts:
(X is younger than Four)
Four's age: 62
X's age: superstitionally 86, but correctly 35.
