First, familiarize yourself with the melody and lyrics. Then, practice hitting the right notes and maintaining the rhythm. It takes some patience and repetition.
I'm not sure exactly as it might be a very specific or even fan - made story. But generally, in the Shrek series, Shrek goes through various adventures, often dealing with his relationships and his identity as an ogre. Maybe in this part 3, he could face new challenges in his marriage with Fiona, or new threats to his home in the swamp.
Kind of. Shrek shows a unique take on love, with the characters overcoming obstacles and discovering their feelings for each other in an unconventional manner.
Well, if it follows the pattern of the Shrek series, Shrek himself would be a main character. And of course, Fiona, his wife. Donkey and Puss in Boots would likely also be main characters as they are Shrek's closest friends.
The Shrek origin story is about an ogre named Shrek who lives alone in a swamp. He is initially a grumpy and solitary creature. One day, his swamp is invaded by various fairy - tale creatures who have been banished there by Lord Farquaad. Shrek decides to go on a journey to see Lord Farquaad to get his swamp back. Along the way, he meets a talking donkey who becomes his sidekick. This journey ultimately leads to his encounter with Princess Fiona, and a whole series of adventures unfold as Shrek's life starts to change in unexpected ways.
