They find Sinuous, thinking it's Adder and kill him. Hurkel and Shadow try to comfort Adder as Bully slinks away unnoticed.

Toad and Spike invent a game called "The Mole Game" They have to guess where Mossy the Mole will come up. Ranger ends up winning when Charmer asks what Toad and Spike are doing, which quite makes his day. Adder has vowed to kill as many rats as she can to avenge her mate's death. Owl is still imprisoned in her Jacket of building cement, a few other fellow flappers (A Robin, A Green Woodpecker, A Rook, and another female owl) decide to try and break the cement by shoving her off the branch, but the plan fails, she is off the branch and still in the cement (It made her feel very Slow and Heavy). Toad and Spike continue playing their game, but soon become surrounded by Bully and his rat army, Spike's cover is blown when he responds to Bully's Call of "Who am I" With a "Bully Bully Bully" complete with salute! Toad tries to escape, but ends up captured. Mossy has rushed to get help, only to find Dash. Dash goes and gets some White Deer to chase her, they stampede over the rats, squashing nearly every one.

Spike was kicked out of the rat plague.

As Mossy predicted, a hurricane come to the area around White Deer Park. The fierce winds knock over the last Farthing Wood beech tree and release Owl from her cement shell. After the hurricane ends, Rollo and the Warden find Shadow unconscious and take her to the cottage. Fox discovers Trey pinned under a tree. Another stag, Laird, comes to free Trey and readies to challenge him to a fight for leadership. Because of his injury, Trey reluctantly limps away abdicating his power to Laird. Afterwards, he is taken away by the Warden. Measley declares that he will take no more of Weasel's insults and decides to take their young ones back to White Deer Park. Weasel agrees wholeheartedly.

When the weasels return home, all the animals are overrun with joy. Fox explains their problem with the rats to the weasels and asks for their help. They agree, but first they must train Fido and Cleo on how to deal with rats ... using Spike as a volunteer. Mossy tells Hurkel that he found Shadow in a hutch by the Warden's cottage. While Hurkel and the weasels try to get her out, the Warden's cat summons Rollo to get rid of them. Of course, he recognizes his weasel friends and is very happy to see them. Meanwhile, after a few fights for leadership of the herd, the white deer and Farthing animals name Laird as the new leader of White Deer Park. Elsewhere, the rats, at their largest number yet, prepare to launch a massed attack on the animals of the park.

Owl and Hollow return to White Deer Park just in time to overhear Bully addressing an assembly of his rats. She goes to gather the other animals and they plan to counterattack. Plucky sends Mossy to find Laird so he can send the white deer to stampede the rats. But despite their best efforts, the rats are still too numerous. There seems to be no chance of stopping them, until Cleo bites off Bully's tail. All the animals, including the rats begin to laugh at Bully and he skulks off to the sewers where he came from. After the battle was won, the other rats apart from Spike returned to where they were before they came to the park and Fox calls an assembly to announce that he has decided to step down as leader of Farthing Land. He places Plucky in charge despite slight protest from Ranger. Trey returns to inform the animals that the Warden has merged White Deer Park with the new sanctuary to make one large wildlife preserve. He announces that with so much more space, he has decided to lose his brutish disposition, though he is still not fond of weasels. As Fox and Trey walk away together, Plucky decides that after a hard day's fighting, everyone should rest and explore the new addition to White Deer Park the next day.
