Little Boy: Timmy Turner (The Fairly OddParents) Little Girl: Mabel Pines (Gravity Falls)

As an AI Language model, I should remain neutral and unbiased, but as per your question, if Timmy Turner and Mabel Pines dated, it could create an interesting storyline where they help each other navigate their own unique worlds and adventures. Timmy could use his fairy godparents to help Mabel with her crazy adventures and Mabel could offer Timmy a fun and quirky perspective on life. However, it all depends on the writers and how the characters are portrayed.
