yes
Dobby's age was never mentioned in the series.
Dobby and Kreacher.
During the first movie Bellatrix lestrainge is torturing them and dobby comes to save them so he elf-aperates them but Bellatrix throws her knife at him and he dies but I cant explain in the amount of space given how they came to be at malfoy manor so watch the movie
He Felt Like It Really. But...Ask Him! :D
Dobby the house-elf told Harry about it .
Dobby died in Harry Potter and the Deathly Hallows.
because DOBBY dies! :O i got that from the book not da movie :)
Never
The movie differed from the book. In the movie it was Neville Longbottom that informed Harry of Gillyweed. In the book it was Dobby the house elf. I agree with the above, but thought I should point out that Dobby is replaced by Neville a lot in the films. In Order of the Phoenix the book, it's Dobby who informs Harry about the Room of Requirement, but in the film, it was, yep, you guessed it, Neville!
They use different things to represent him. In the final movie they used actors with Dwarfism.
No. Lorde has never appeared in a Harry Potter movie.
Dobby is a house elf. They serve wizarding families like slaves and can only be freed if they are presented with any type of clothing by their master.
