Most of the BP's I've owned were distinctly different, especially Yukon and Drizzle. Yukon being unusually bombproof and relaxed (he wouldn't survive a day in the wild, natural selection would've taken him out years ago by his personality alone HAHA) and Drizzle being unusually shy and defensive. They're out of the norm in their own way, so they're special to me.
A couple others were relatively similar... the same old same old average but docile nervousness- get a little scared when I reach in and they ball up when they're handled, rarely displayed inquisitiveness and never really relaxed. Always wanting to just move away and find a place to hide. Those didn't have much individual personality. So I sold them LOL.
