The Animals of Farthing Wood S03E01 Comings and Goings
The Great White Stag goes to take a drink from a stream near the boundary. Many of the animals have had children and even grandchildren. Fox's grandson Plucky wanted a race with Dash. Weasel is going to have children which Weasel was not happy about. Whistler who was flying around White Deer Park sees the Great White Stag at the stream he was drinking from with his head nearly touching the water with his eyes closed and then he collapsed. Whistler realized that he perished from drinking and that the Stream was poisoned. He went and alerted Fox and the other animals. Fox had figured out that a bad tempered Deer named Trey would take his place.
Owl had flown away to go look for a Mate. Meanwhile, a group of rats led by a big white rat named Bully come scurrying through the fence and head towards the Great White Stag's dead body. Elsewhere, when Plucky and Dash take a drink at a pond, They get encountered by Trey and he tells them that it's his pond he will not let Non-Deer drink from it. The rats had been watching and they were about to capture Mossy until Measly scared them away. The Weasels had a great chase from Trey from that screaming who prevents screaming happening in White Deer Park. Weasel had decided for she and Measly to leave White Deer Park. Meanwhile, Shadow the Badger arrives at White Deer Park with a mate named Hurkel and a Snake named Sinuous who mates Adder and some Voles arrive at the Park as well.
