Harry Potter and the Goblet of Fire
Despite chamions not being allowed to know, Hagrid covertly reveals to Harry that the first task is to get past a dragon. Harry struggles to think of a way past a dragon, until Moody suggests flying. Hermione helps him to perfect a Summoning Charm, which he uses to summon his Firebolt broomstick and fly past the dragon to retrieve a golden egg, receiving high marks from the judges. Harry's egg is supposed to contain a clue to the next task, but when opened it merely shrieks loudly. Later, Cedric tells Harry to take the egg into the bath in the prefects' bathroom to work out the clue.
