1) Shouldn't that be FIVE cute girls? Scarlet has established that Kat is only a short distance away.
2) Looking past the impossibly thin gene pool that would be involved here... is that even possible in the SA universe? Males consisting only of a human and penguin, Females consisting of a cat and four squirrels. Or was Pip just being incredibly silly?
3) With the rest of the Earth destroyed, who would Pip buy comics, games and videos from?
(PS - A far more sensible approach would be for those four sciuridae geniuses to clone as many of the deceased as possible.)
