Troy gives a speech to his fellow Wildcats, explaining how they're, "All in this together" and ends the speech with "Once a Wildcat, always a Wildcat."
Troy receives his diploma and jumps of the stage, down onto the field. The rest of the Wildcats join together to form their mascot logo from a bird's eye view. They proceed to throw their graduation caps off into the air and perform the movies last choreographed number, 'High School Musical'.
At the end of the song, the 5 main characters (Troy, Gabriella, Sharpay, Ryan, Chad & Taylor), all hold hands and skip towards the camera. They stop, turn around, the curtains close and they raise their arms up, the High School Musical logo is lit up and slowly comes down. As the camera pans back down, the 5 characters are now on the stage. They walk towards the camera and jump (like in all the movies posters). This image is frozen for about 5-7 seconds. They then all stand on the stage, whilst the last chorus of 'High School Musical' plays one last time. The camera shows a close up of each character's face, then they bow and the curtains close for the last time.
