We don't have baby metroids as companions, no. We don't have actual babies as babies, no.
But we do have something cuter than babies, and that's our cute and cuddly (thank the all mighty for not life sucking... okay maybe) pets that we may or may not baby... >.>
I just want to see all the cute animals.
It's a little blurry but...
@metroid3d kitty cute, but needs more Metroid XD
