Okay hi, sorry I spent Way To Long thinking about this (which is probably good, I love to think about my little guys). This definitely gave me a lot to think about so mission accomplished with this killing some time lol.
As of right now the three of them haven't gone on any big adventure yet (something that Savvie would Love to maybe fix one day) but in the meantime they get to do smaller things to pass the time.
Gimmick is still trying to practice his magic acts and so a lot of times Savvie will be there to help hype him up. Pallete will show some support too but she isn't exactly the type to express it super well. He still gets incredibly nervous and doubts himself Way to much, something that Savvie really wants to help him overcome. One idea they had to solve this was doing practice shows in front of Savvie and Pallete to help him break through his worries.

Pallete is always cooped up indoors and rarely ever wants to go outside, so Savvie and Gimmick will try and invite her out to places to help get her outside more. She does enjoy desserts and sweets so they'll often go to any places that offer them if its up to her. When they're not inviting her out, the two will sometimes visit her and keep her company as she draws. Surprisingly, despite being a bit of a reclusive person, she doesn't mind the company if its the two of them. The two work as good models if she needs some reference for painting too.

Savvie is usually tucked away in their own makeshift garage trying to come up with all sorts of gizmos and contraptions but once a project of theirs is completed, oftentimes they'll get either Gimmick or Pallete to test it for feedback. There's a lot of duds, but every now and then there's strokes of genius. For reasons, Savvie lives alone on the outskirts of town so they can get pretty lonely, with nothing but their work to keep them company, so having Gimmick and Pallete around is always something they look forward to.

So for now its a lot of small, day to day things but maybe one day they'll get to leave town and really see what's out there. If anything, they're just glad that they can hang out together and have a good time.

~Thank you for the question!~
this is so great! I feel like I got to learn a lot about all of them.
