Amphibian Swamp 
Headcanons: I believe in some more than others
Sparky isn’t as popular as Pipp and never will be
Pipp’s friend, Jazz can’t swim
In the Mane Melody Trio Jazz is the youngest, about at least one younger than Pipp at least. Maybe about 17-19? While Pipp is around 18-20. Rocky is the oldest, being around 210-23.
Rocky is already married, or at least he already has a girlfriend
In the Mane 5 Hitch is the oldest and Pipp is the youngest
Trixie is only around 18-20
Trixie roams the G5 world happily (This is true in my own canon)
