Perhaps it's a new character, like an evil wizard who has heard about the power of Shrek's family. He believes that by getting rid of the ogre babies, he can gain control over the swamp and all of Far Far Away. So he devises various evil plans to harm them.
One possible plot could be that the ogre babies fall ill due to a magic spell gone wrong in the swamp. The spell could have been cast by a vengeful fairy who was angry at Shrek for some reason. Shrek and Fiona then have to go on a journey to find the antidote to save their babies.
One aspect that makes it an interesting concept is the potential for character development. Shrek, who has his own set of insecurities and growth throughout the original movies, could have a whole new arc when paired with the Do the Roar Kid. The kid could bring out a different side of Shrek, perhaps a more nurturing or patient side. And for the Do the Roar Kid, being with Shrek could give them a chance to learn about different worlds and grow in their own way. Also, the humor that could come from their interactions, like Shrek being all grumpy and the kid being overly enthusiastic, would be great in a fanfic.
Well, I'm not sure of specific 'Shrek x Do the Roar Kid' fanfic stories off the top of my head. But you could try searching on some popular fanfic websites like Archive of Our Own. They might have some interesting takes on this rather unique pairing.
