I have two friends I met twice at the CCG, I friended them after winning with them a second time: Sugar and Spice. They were both brown mice with pink-ish shirt, Sugar had a white skirt (Girl) and Spice had white shorts. (boy) They were both about 95 laff last I remember. =D But yeah, that's awesome but used. I think they might go on TTC, since they were CCGing, but I dunno.
EDIT: Me and my sister just thought of some, sorry if they're taken, haven't seen them anywhere;
Dora and Boots! (Boots could be a monkey, and Dora'll be a brown mouse or something)
Pancake and Syrup work, foscho! =P
Mario and Luigi, a red and green whatever!
Or to add to the above, Waluigi and Wario too, purple and yellow. Then you get quadruplets! =P
Also, nobody use this, but this cat I saw had th awesome name of Cheetah Cheetah Pumpkin Eater. They'd match with Lion Lion Pants On fire. =P
