This is all she told me, it isn't that new and it's a kids film and its about a world where there are these monsters that are called something like 'kidune' and their 'king' and a human had a child together and he's orange and eats coal .then he starts at a new school and starts breathing fire cause he was getting chased and when he goes to a party his dad finds him.and then after that he can do all kind of crazy things and then at their prom they get attacked and he does his weird thing.

Was it animated?

Sounds like,.

FireBreather (2010)

"she told me, it isnt that new"
Hmmm,. The history of cinema is over
100 years old.This movie's about 18 months old...

Sounds relatively recent to me.
