(I know Aika from Pretty Pretty Please I Don't Want To Be A Magical Girl is cool, but idk why this indie series is so underrated if this is so good).

Some my fav characters with unknown heights:

C00lkidd (Forsaken): I mean all of the characters are having blocky and R6 type. So I suggest it's unknown for him, but he is 11 years old, I can't imagine how young he is with an average height of an adult man.

Cream Puff Cookie (Cookie Run): Basically cookies are created by the witches. Cookies are like maybe 2/3 height of a witch hand so it's unknown. Cream Puff Cookie is a child cookie and she is so short than Latte Cookie, so... I'm not sure for her height, but possible around 5cm or smth idk. I'm suggesting cookies tall may be unknown.

Party Goober (Regretevator): Same this is unknown. He's just an average tall of a roblox player.

Pomni (The Amazing Digital Circus): Of course I'm not gonna measure her height if she is stuck inside a game and her real life appearance is unknown 💀

Agent 8 (Splatoon 2-3): Well her height seems grow taller. But I heard octolings are taller than inklings. Idk if she is no longer 4 ft tall. I suggest it's unknown bc some ppl only theorizing Agent 8's former tall (Splatoon 2), but not her height now (Splatoon 3). Normally Octolings are around 5 ft tall.
