Bear Behaving Badly - Season 4 (2010)

After Barney has read Nev a story about wizards Nev wakes in the night to discover a door in the wall behind which is the Magic School of Magic and Magic Stuff,where Nev learns how to become an ursine Harry Potter. Unfortunately he must also battle the evil Voldy Prank who aims to keep him a prisoner in order to make blue bear ice cream from his fur.

Aunt Barbara wants a lawn in the backyard where her dog Chops can play. Mr. Prank gets the grass seeds and Wonder Grow powder but accidentally drops them in the flat whilst chasing Nev. Consequently the flat becomes overcome with grass and not only that but Chops also grows in size. Things must be rectified before Aunt Barbara finds out.

Barney gets Nev a set of miniature golf clubs and asks Mr. prank to give the bear lessons in the game. Inevitably the lessons soon turn into a grudge match with Mr. Prank cheating in order to beat Nev. Fortunately for Nev Crazy Keith intervenes in order to give him a chance to win.

When Barney gets himself an electric skate-board Melanie is envious but cannot afford to buy one. However when the beauty salon to which Aunt Barbara goes has to close she has a money-making idea. She will open her own health spa in the flat. In fact it does very well and the customers pour in but she needs to rope in Nev to keep it all from Mr. Prank.

Barney discovers a old musical box that belonged to Uncle Rupert but when it is opened it turns out that it plays no music but causes people to sing the truth,uncovering secrets in the process. Nev is now under pressure not to tell Aunt Barbara about Crazy Keith living under the floor-boards but,for all his best endeavours,Aunt Barbara still ends up with a bear in her bed.

Crazy Keith wins a year's supply of sticky toffee puddings which he and Nev consume in one sitting,causing Nev to hiccup little woolly creatures called Wibbles which fill the flat and start eating the furniture. Can Nev sing them all to sleep and Beatrice take them to the zoo before Barney returns?

Mr. Prank buys a security system to safeguard his ice cream but it goes berserk,engulfing Postie,Aunt Barbara and Prank in its tentacles. Nev and Crazy Keith - disguised as a Ninja duck - manage to disable it and Keith is rewarded with ice cream for his anniversary dinner with Doris.

Whilst Aunt Barbara is away her eccentric sister Alice comes to visit, a woman who believes she is Alice in Wonderland, complete with pet white rabbit and potions which cause Nev to grow and shrink in size, to say nothing of the flood that deluges the flat. Alice declares Mr. Prank a hero when he finds her missing pet rabbit but Aunt Barbara is less forgiving when she returns to see the mess the flat is in.

Crazy Keith and Nev escape after trying to blow up the cupboard where Mr. Prank stores his ice cream but Doris is left behind and given to Bandit the cat to play with. After unsuccessful efforts to rescue her Crazy Keith stages a trampolining contest between Nev and Bandit with Doris as the prize for the winner.

To get Nev and Barney evicted Mr. Prank hides Barney's overdue library book and then alerts the local press to tell them that Barney has stolen it. Crazy Keith and Nev get into Prank's flat to retrieve it and manage to expose him to Beatrice and Aunt Barbara,who gives him the sack. However, Barney has his reasons for getting her to change her mind.
