Grumpy

Grumpy is, hence his name, a very grumpy dwarf who lives off cheese. He takes dumps a lot and watches Markipiler too. He calls Bugs Bunny "Dopey" because he has big ears like Dopey the dwarf and he calls Waluigi "Sneezy" because he has a pink nose like Sneezy which makes him look like he has been sneezing a lot. He also says "HO-HO-HO!" a lot because of the Heigh-Ho Song. Most of his character was revealed in Woody and Daffy Duck watches Snow White and the Seven Dwarfs,  like him hating all elves (except for Link for stealing his cheese. His birthday is also February 3 as well.

Age
It is unclear how old Grumpy is. In Looney Tunes Goes To the Pool (2016),

it is revealed that Grumpy is 63 years old. In various videos made in 2017,

it is revealed that he is 64 years old. If Grumpy was 63 in 2016 and 64 in

2017, he'd have to be born in 1953. Snow White and the Seven Dwarfs

was released in 1937, so 1953 can't be his birth year. In Woody and

Daffy Watches Snow White and the Seven Dwarfs (2017), Grumpy says

he was 44 when Snow White and the Seven Dwarfs was released. If he

was 44 in 1937, he would've been 125 in 2017 and he'd be 129 now.
