I am in the out of the abyss campaign playing a dragonborn, We stole a dragon egg and hatched it and It bonded with my character, We ended up calling her Nala.

 

A red dragon knows the value and provenance of every item in its hoard, along with each item’s exact location. It might notice the absence of a single coin, igniting its rage as it tracks down and slays the thief without mercy. If the thief can’t be found, the dragon goes on a rampage, laying waste to towns and villages in an attempt to sate its wrath.

Somebody's got severe anger management issues :P

Wyrmlings coukd also have the Abyssal Chickens "Bad Flyer" as well if you want to make it more fair for people who don't really have access to fly yet.

For example. I have a 30-foot wall that a character wants to run up who has good acrobatics. He rolls a natural 20. Does he run-up? No, because no matter how good at acrobatics or physically strong you are, you can't just run up a sheer surface. So maybe the result is they get 7-10 feet up, fall, but don't take any bludgeoning damage.

This is bad DMing, if there's 0 chance of Success(even on a natural 20, +modifiers, guidance, etc) then why would you make the player roll for it in the first place. All you do is waste everyone's time and ruin what could be an otherworldly cool moment for the players AFTER the nat 20 happens. For me, that nat20 would be the character channeling their most "once in a life time" bad ass inner monk(which literally have the impossibility you describe baked into their class) and through sheer luck, manage through their movement and action just enough traction to somehow make it up.

 I agree with your base point, that you have the ability to say no, but if the answer is NO, Don't punish your players on top of it.

And to your other point... I LOVE when a player rolls a Nat 20 on seducing a dragon... That player didn't realize the dragon is a power top that is into some things most mortals couldn't dream of surviving... He Better pray he has enough spell slots worth of healing to survive.

In reality, something like a Nat 20 on a dragon would be amusing it enough to not instantly make it tear you apart. 

This guy can deal up to 13d6 fire damage in a round

 Most dragons that are Adult or older usually can, either through a natural ability or some magic they learned as they grew (they could even be an actual druid or sorcerer), and some young dragons might figure those things out a bit earlier in life, but for a wyrmling it's practically impossible.

my barbarian character is obsessed with how to train your dragon, and tried to TAME this thing 

DEX modifier is initiative 

it has kind of a lot of hit points for a baby

Is it possible to tame this as a level 10 ranger?? Or am I stupid... and would it grow up over time if I did tame it.

 Just saying, Nat 20 is only really a "Crit auto success" in attacks rolls, and in everything else it's just a maximum possible roll. If the DC of something is, per example, 25 and a character rolls a Nat 20, but only have a +2 modifier, he stills fails in the task :)

wisdom is +0

If a red dragon wyrmling had been adopted when it was very young..and grew at the side of a human..would it be able to already know Common or grow some sort of loyalty to that person? Like if that person is his "treasure"?

To some degree. Dragons have a sort of racial memory like aboleths just not nearly as intense. A newborn red dragon will still have a glimmer or arrogance, greed, and sadism natural to the species and will learn more about those things as it grows up. My group was given a red dragon egg as a reward by another dragon they're working for (it's a long story involving lots of alcohol and family drama) and when it hatched, they made friends with it through playing up its ego. Hamlet the wyrmling is given "tribute" regularly (spare gold because this party is rich), has his own lair (an apartment they pay the rent for unbeknownst to him), and gets a cut of any loot he helps them discover on adventures. Mind you even with all of this he regularly tries to kill the druid's pseudodragon for not groveling to him and has eaten at least one innocent halfling grandma.

No monster has a fixed initiative, when you have the encounter you roll.

My team is trying to seduce him help!

 this is how to solve every one of these problems: make ONE member of the team do an animal handling check, and make the DC 25, or 30 if the PC doing the check is of 15th level or higher. They'll never succeed. Make it so that if the initial check fails, any additional checks made will automatically fail.

Dex is +0
