Surely adding kids to the cast will make the show more whimsical and fun, right? Um, no ... because exactly one episode later, this happens:
They couldn't have known they were trespassing on Vlad the Bluejay's territory.
Holy shit -- there's more gore in that scene than in the entire second season of The Walking Dead. Yes, those are the newly born baby mice impaled on a thicket of thorns.
They weren't just killed off subtly off screen: We needed to witness their horrible deaths, for some reason, and then watch their mother crying in sadness and guilt. Why introduce a litter of babies only to have them snatched away an episode later?
"Chill out, lady. They were basically strangers."
And this wasn't a one-time thing -- in another episode, the group is found out while hiding on a farm, and one of them, Mrs. Pheasant, is shot and killed by a human. Oh, but that's not the unusually cruel part yet: After the group has managed to escape, they notice that one of the animals was left behind, and the recently widowed Mr. Pheasant volunteers to go back and get them. If you already know where this is going, you are one sick individual.
"Mummy, I'm a vegetarian now." "Oh, get over yourself, honey."
