I like Cutsie Danny, as well! Best Danny would be a combination of Baby Danny and Cutsie Danny. Though, having him have at least SOME muscle development isn't necessarily a bad thing; ghost fighting needs a positive payout, after all. More realistic that way. And I don't really support the idea of him becoming a brick house when he's older- then again, I don't really support the theory of him aging at all throughout the series, either; no birthdays are mentioned, and the only given age is 14. Plus, 14 would be when he's at his smallest and babby-est, so that automatically makes him the best Dabby. Make him the tiniest out of everyone (his friends must be pretty dang tiny, too- but that's good; small friends stick together).
Cutsie Danny is my favorite Danny. The animation in this style is very expressive, and the action scenes have the most motion. All three of the original Dannys are good Dannys, though. Season three broke my baby.
I do agree that it’s important for him to grow a little, though. At least in terms of muscle. All that ghost fighting would eventually have an effect. If I made the rules, though, he’d always be mostly a tiny noodle. Especially in human form. If his hair can change from hat hair to his usual style when he changes forms, I’d say it’s likely the muscle tone would be exclusive to Phantom, too.
Personally, I’d say he’s maybe 15 by the end. It’s true that no birthdays are mentioned, but season ends with the beginning of summer vacation. Season 3 is a huge mess, so figuring out continuity from there is hard, but they are shown in school a couple times, so we can probably guess they started Sophmore year. Thooough, Claw of the Wild also claims they’re still on summer vacation, and that’s the third-to-last episode so it’s up in the air.
And yes, Danny is very tiny. I did this awhile ago with Maternal Instinct, but I’m about 5′6, which is around average height for a white woman. Assuming Maddie’s about average height, I attempted to figure out Danny’s height.
It’s pretty inconsistent, but I’d probably say he comes up to somewhere between the bottom of her earlobe and the middle of her neck. Measured against me, that puts him somewhere between 4′9 and 5′0.
But if you think that’s tiny:
