I snagged Bar (male common jollin) from the pound because I like the name but honestly I have no plans for them. Obviously their TC is gonna be full of bar related items, but I don't know what color/species to go for, or if they should be a bartender, a regular, a bouncer of sorts, etc etc.

Any and all suggestions are appreciated!

Happy birthday, for starters. :)

I'd personally go for a blacklight ("BL" further down in post) pet color, since bars remind me of cocktails and cocktails usually = party. But that all depends on what type of bar you've got in mind. In that case, maybe a BL Chai (especially if it gets an overlay where it's holding a drink in it's paw), BL Clawsion ("No, thanks, I'm done for the evening.") or BL Jollin (kinda tipsy, enjoying a good joke/company at the bar) would be a good choice, especially if going in a more comic-relief way with the pet.

Also, I like the bartender idea the most, but I've also never (yet) ran into a bouncer type of pet, so that'd be an interesting approach, too! I wish you the best of luck with Bar either way. :)
