So, if you've ever heard of the show BFDI, I have decided to try and use the MBTI to type each character.
If you don't know what the MBTI is, or BFDI, I'll supply some links.

*I AM NOT MEANT TO OFFEND ANYONE OF ANY PERSONALITY TYPE OR OF THEIR FAVORITE CHARACTER*

Anyways, let's begin!
Woody- IxFJ (worries a lot, makes sense for an IFJ.) Couldn't decide S or N though.
Pin- ESTJ Bossy, but helpful
Needy Needle- ISTJ kinda a bland character tbh. couldn't think of anything that could make more sense.
Teardrop- IxTx- hard to find S/N or J/P. I know you're confused about the T instead of F, but when you unfold her personality she's clearly a T.
Golf Ball- ENTJ- Bossy and analytical.
Coiny- xSxx- blander than needle. Hating on another bland character doesn't give you any more personality.
Snowball- ESFx- The big, dumb guy.
Match- xSTJ- Selfish and lazy.
Eraser- ESxP- Similar to snowball, but a bit smarter.
Pen- ESTP- the funny, crazy guy.
Blocky- ESTP- Same as pen.
Tennis Ball- INTx- the analyst.
Pencil- xSTx- a bit more forgiving than match.
David- xxxx (Aww, seriously?!)
Ice cube- ISFJ- sort of the cute character.
Rocky- xSFP- cuter than I.C.
Spongy- INFP- sort of the rejected character of the show
Flower- xxTJ- evil, to say the least.
Bubble- ExFP- kinda the happy-go-lucky kind of character in the show tbh.
Leafy (before finale)- ENFx- very kind and accepting.
Leafy (after finale)- xSTJ- jealous of losing and LITERALLY becomes evil.
Firey- xSxx- Carbon copy of coiny.

I might do BFDIA characters in the future. What do you guys think?

Wow this is so cringe. I didn't even use the functions…

What do you think about the BFDIA characters?
My opinion on some:
Gelatin: ENTP - laid-back and analytical, but a bit ditzy at points
Fries: INTJ - grumpy and serious
Dora: xxxx - honestly really bland
Yellow Face: ExFP - eccentric like an ENFP, but also extremely happy like an ESFP, so I couldn't decide
Donut: ExTP - aggressive and impulsive

The function knight inside of me is screaming-

uh, Ice Cube seems pretty Fi oriented (her acts of revenge are value-based) so I'll go with IxFP

Leafy is EsFJ in both versions methinks

Golf Ball is smart but that doesn't make her intuitive, ESTJ?

Firey and Coiny both I'd vouch for ESFP

Needle was more of a running gag than anything, I'd say ISFP though. god, a lot of FPs

wanna say INTJ for teardrop without any proper justification though

Yeah
as I said in one of my other posts, this is really cringey.
Ice Cube I TOTALLY Agree with you on.
I picked ENTJ over ESTJ because golf ball uses her intuition to assign jobs to her teammates, so yeah. Your'e probably right tho.
Don't see anything against your Firey and Coiny decision.
Needle-alright.
I think I placed TD in my new chart. I have it with me, but I think I need to make some adjustments.
