You mean we get a say in which minor imaginary friends appear in the house? Awesome! In that case, I cast my vote for Crackers, Red and Gary.
The only potential problem I can foresee with creating a Crackers Sim is that no one can quite agree upon the issue of “his” gender - I’ve always seen him as a male myself, but that’s just my own intuition. Perhaps if they include him in a future Gallery of Friends it’ll put an end to that debate once and for all. Until then, I’m assuming it’s not possible to make a Sim who’s completely and utterly androgynous? Or that you can alter their gender at a later point?
Either way, I see Crackers and Red as being reasonably outgoing and active, as opposed to Gary, who strikes me as being pretty timid and lethargic, and I think all that three of them would have very friendly temperaments. Gary would be mostly serious - his two cameo appearences in the series suggest that he's a pretty downcast kitty overall who's nonetheless able to put on a happy face at the drop of a hat. Crackers is also highly sensitive, but I think that he'd be largely playful when he hasn't had to face rejection. Red would be mid-way between serious and playful - he has a light-hearted attitude toward life but still takes it seriously enough to be distressed by the actions of others. He of course, should have a strong interest in animals and the environment.
Erm, well, those are just some suggestions, and probably not very useful. However you decide to play things, I wish you luck and look forward to seeing the end results.
