Is he/she a boy/girl? Well...
I personally think it's supposed to be unknown, or neither.
That's like a running joke in the series.
You CAN argue, however, for both. If you think he/she's a girl,
then don't use terrible reasoning such as this: Because he/she is
voiced by a girl. No, that won't work because Bart Simpson from the
(duh) is voiced by a girl and he's a boy, so that won't work. It
also won't work if you say that flaky is a girl because he/she was
being flirted on by Disco Bear, because Disco Bear wasn't flirting,
(episode: ski ya, wouldn't wanna be ya) he was talking all
cool-like. The way he always acts.
Flaky is also NOT a dude just because of the dandruff flakes,
ok? That just doesn't make sense. and in the episode Something
Fishy, don't say he/she's in the boys bathroom, because you can't
tell which bathroom he/she is in. Besides, that just proves my
point that it's supposed to be unknown.
Such as this: In that episode, Flaky is having a hard time
deciding which bathroom to go into, so therefore the joke is
present. Also: Maybe in some episodes he/she is a girl and some
episodes he/she is a boy, it all depends on which role he/she is
supposed to play. Just like the other Some episodes they're kids,
in some they're adults. It all just depends on what episode it
is.
That's all Ive got. Hope it made sense.
Flaky is confirmed to be a girl by Mondo Media when they refer
to Flaky in a video description by using the word "her". Her voice
actress, Nica Lorber, also confirmed Flaky to be a girl. Other
voice actors said Flaky is a girl too.
