Go towards Hagrids hut and to the left of you, there will be a light which
comes up from the ground, these are Doxys. Kill all of them using Flipendo and
then switch characters to Harry and pull the eggs off the trees using Carpe 
Retractum, if you get poisned use the potion. After you have 3 eggs go to 
Buck Beak by Hagrids hut and get on him, fly towards the light over by the boat
house so that you can get the seahorses. Use Carpe Retractum to pull the sea
horses in. Get back on Buck Beak and fly to a courtyard that has a fountain in
the middle.

Using Hermione use Dragonifors on the dragon statue so it burns the dragon 
flies, a good tip here is to use the spell just as the Dragon Flies are coming
back, this will make it easier to get all 3 and does not waste time.

Head back to the potions classroom, there will be another cutscene and you 
find out that the balls for Quidditch have been swapped over. So run down to
Hargrids hut and using Hermione climb on Buck Beak, fly to the courtyard which
you previously could not get to because it is surrounded by the corridors, get
off Buck Beak and freeze the Ice Puddle, climb up, use the Dragonifors spell on
the dragon and then the balls will be free, quickly climb back on Buck Beak and
then fly to the left hand side of you, this is the quidditch stadium, it has 4
flags outside, land here and walk up to the gate, time has now flown by and you
are now on.....
