The Familyverse’s two obnoxious pseudo foils….Gamz and Tabby
 
Gamma Light  
“Gamz”, “Gamz Le Puissant et Fabuleux”  
Inspiration: https://www.youtube.com/watch?v=1d7oIpD5VSY  
Madame Mousey from An American Tail  
Parents: Starlight Glimmer and Ember [Fizzle is the surrogate…he’s the white male dragon from that Spike episode. He’s not in the relationship only offered to “help out”. Starlight is the birth mother]
 
Tabitha Treelove  
“Tabby”, “Kitten”  
Parents: Trixie and Treehugger [Double Diamond is the donor…he’s unaware of Tabby’s existence]
 
Gamz is the dramatic and emotional child of Starlight Glimmer and Ember the Dragon Lord while Tabby is the demurred and often overlooked daughter of Treehugger and Trixie [HUGXIE!!!] Gamz was always academically gifted, being a creature of great prowess for linguistic, his street smarts however always seemed to lack. That being said, his better half Tabby had nothing but street smarts to rely on, never doing very well in her classes mostly from a lack of trying.  
The two came together and created a small caravan so they could explore the lands as travelling minstrels! Gamz being an impressive vocalist and saccharine mandolin player while lil ol’ Tabby is a devote and sheepish flautist.  
That being said, Tabby is hesitant to venture too far as she very much loves her moms.  
Though they do have hobbies and talents of their own, they do like to be little nuisances toward the mane 6 kids. They are comically incompetent though and their antics are more annoying than malicious.
