We named them after 2 of Ben's favorite female video heroines...Samis is a warrior soldier in the Metroid series, and Zelda is the goddess/princess in the Legend of Zelda series.
Wait, what? Uh, oh...it seems Zelda needs a new name...maybe Mr. Zelda! Turns out little Samis is going to be a mommy. Didn't see that one coming. I mean, really, we didn't see it. They were sold as 2 females and I double checked. Even after I realized that Samis was with piglet. Mr. Zelda is one sneaky pig!
