Summary
Ozzie chuckled, rubbing a claw gently over the imp's head. "Four cheeses, huh? If I give ya that many, you'll be meltin' into goo before we're done."
Fizz gasped like that was the best thing in the world. "Cheese goo!!" he squeaked, clapping his hands.
By the time Ozzie set him down on the counter (carefully, on a soft cushion he kept there just for his tiny imp), Fizz was already bouncing with excitement. He stretched his long limbs toward the fridge dramatically, making grabby hands.
"Burgerrrrr!" he whined.
"Patience, baby," Ozzie soothed, sliding the fridge open. "Papa's got you."

Summary
Blitzø has a secret that he's kept to himself for a long time. But what happens when a certain owl discovers that secret?
One thing's for sure is that Blitzø will certainly be in for a wild ride... A ride full of baby talking, bottles, and diaper changes...
This is my first story on AO3, so I hope you guys like it!

Summary
Classification AU:
Blitzø didn’t have a great childhood, he had to grow up really fast and take on a lot of responsibility to help his family. And now he’s a successful assassin, a badass.
Fizzarolli’s always been an icon, always had to be perfect, had to be funny, had to entertain…otherwise he was a failure. He made a lot of sacrifices to achieve this level of perfection.
Is it any wonder they cheated on their classification test? What would people think if they knew what they really were?
