We have a million!!!
Kito--the inu, shiba inu, snob, pumpkin, sweetie
Abbey--the Crab, crabby Abbey, Abbers, flabby Abbey (she's getting a little thick), not so shabby Abbey, clumsy, goofball
Riley--Rileymonster, Rileykins, Kinser, Kinsey, ri-ri, silly

Anything that rhymes with their names usually comes out, and any other thing that comes to mind--Abbey comes to "Crabby", it's pretty funny
