Walkthrough
Disclaimer: This walkthrough will feature the gameplay from the perspective of a Year 2 student. Since the adventure is available for students of Year 1 and above, the star and attribute requirements for certain tasks might be different for you, depending on your current progress of the main story.
When you arrive, you’ll be able to interact with some of the characters. To do so, tap on the speech bubbles above them.
You’ll then approach Mr. Filch and ask him to attend Hagrid’s birthday party. He will not believe you at first, thinking that this is some kind of trick.

He’ll ask you for a reason to attend Hagrid’s party. You have three options to respond with. Since all of those lead to the same outcome, you might as well select the third one in order to gain the most attribute points.

Convincing Filch to attend Hagrid’s party is your next task. To complete it, you need to earn five stars within one hour (three hours for students of Year 5 and above). One star is required to pass for Year 1-2 students. All five stars are required to pass for Year 3+ students.

Simply follow the usual routine for this – tap on the glowing objects to complete actions. This will fill up the star meter and earn you stars. There is a bonus progress action tied to Mr. Filch, so you might want to prioritize his actions to save a bit of energy.

Once you are done, the caretaker will be convinced to attend the party. For your next task, proceed to the Training Grounds to meet the Headmaster.
When you arrive, you’ll notice the speech bubbles above some characters. Tap on those to see what they have to say.
Professor Dumbledore will then ask you to babysit Fang while he and Hagrid finish some urgent business in Hogsmeade. Once they leave, you’ll get three options to entertain Fang.

If you completed the adventure to become an Animagus, you’ll get one of the rare opportunities to use this ability. You’ll then be able to witness a heartwarming scene in which your character plays with Fang.

You’ll then get a task to babysit Fang. To complete it, you will need to earn five stars within three hours (8 hours for students of Year 3 and above). One star is required to pass.

Do this like any other story task and you shouldn’t have much trouble with it. There is a bonus progress action tied to your character, so prioritize that one if you want to save some energy.

Once the task is finished, Dumbledore and Hagrid will return. Hagrid will be very happy to see you and Fang.
The Headmaster will ask you to continue informing others about the event. The next person to ask is Professor Snape. Thankfully, your friends have offered their help and are waiting for you in the Artefact Room.
The plan involves getting some rare potion ingredients and bringing them to Snape. Hopefully, that will be enough to convince him to come to the party. Penny will have an idea of what Snape would find useful.
This task requires earning five stars within an hour. All five stars are required to pass. Because of that, you should consider having a full energy bar prior to starting it.

Complete this just like any other story task and you’ll be done in no time. You should easily be able to finish this task with one full energy bar.
When you are done, you’ll have plenty of potion ingredients that Professor Snape will definitely find useful.

Shortly after, the Third Part of this adventure will be completed. Hit the Collect button to claim your reward. You will receive 3 Gems.
Hopefully, those ingredients will be enough to persuade Snape to attend the party. But things are never certain with him. What if he refuses? Will there be an alternative way of convincing him? And what about your present? What will you get for Hagrid? Find out the answers to all those questions and much more in the fourth and final part of this amazing adventure!
Thank you for reading.
