Bear Behaving Badly - Season 3 (2009)

Melanie brings Clooney, the school's pet guinea pig, to the flat but he escapes from his cage and ends up going under the floor-boards and into Crazy Keith's hide-out. Keith becomes concerned that his beloved Doris is falling for Clooney and so, helped by Nev, he performs a series of dare-devil stunts to win her back again.

Once again Mr. Prank has come last in the Historical Care-Taking Reenactment Society's games and he is not happy. Barney suggests he might feel better coming next to last so he decides to get Nev to join the society on the assumption that a blue bear could never do better than him. Nev, however, is determined and has Crazy Keith to coach him for victory.

Feeling his age Mr. Prank adds rejuvenating tonic to his bathwater but, thanks to Nev, he uses too much and turns into a baby, calling Nev and Keith his Daddy and Mummy. They discover that the antidote to get him back to normal is to tickle him but they overdo it, ending up by ageing him. There is just enough tonic left to try and save the day before Aunt Barbara gives him the sack.

Nev and Crazy Keith make a papier-mache mask but it frightens people so much Melanie throws it out. Then it gets stuck on Mr. Prank's head. He has had dental work and cannot speak so he chases people to get them to remove it but it only scares them the more so. Aunt Barbara sees this as an excuse to sack him. When Nev learns the truth will he speak up for his natural enemy?

Crazy Keith is running his radio station, Radio Doris, from his lair, including an agony line featuring Auntie Kath - who is also Keith. Frustrated by Nev, Mr. Prank rings Auntie Kath for advice, only to be told that, in order to make himself feel good, he should give Nev ice cream. Not that it works, of course, and the chase is on, ending in the basement where Aunt Barbara has got locked in and sees Nev as her saviour.

Nev and Crazy Keith fall through a magic mirror into a parallel universe where Mr. Prank is a kindly friend and Barney the villainous caretaker. Crazy Keith has a bookish twin and Beatrice wants to make a coat out of Nev. Will Nev and crazy Keith remember the password to get back through the mirror into their flat and escape her clutches?

A well-spoken blue bear who resembles Nev calls at the flat. He is Dev and claims to be Nev's long-lost cousin but he has horns and a demonic laugh and is actually an evil genius who has escaped from prison and is out to conquer the world. He hypnotises the humans into obeying him, leaving Nev and Crazy Keith as the world's only safeguard against his satanic plan.

Short-listed for the Caretaker of the Year finals, Mr. Prank needs to look smart for his photo shoot and picks out a coat left by a previous tenant to wear. Unfortunately he was mad scientist Gunther Von Prank and his spirit possesses the coat, turning Mr. Prank into an evil genius. If he is to win the title and the accompanying holiday which will give them a rest from him, Nev and Crazy Keith have to get the coat off him. Cue Nev to spatter it with ice cream.

When a meteorite lands in the flat Nev and Crazy Keith have fun at Mr. Prank's expense by pretending to be aliens and getting him to wait on them. He soon sees through them but when a real alien comes out of the meteorite he assumes this too is a hoaxer until it ties him up to experiment on him. Crazy Keith stalls the alien by pretending to be an inter-galactic parking policeman whilst Nev has to work out how to turn off the alien's machine and send the meteorite back into space.

When Mr. Prank declares that he is resigning his job to travel the world using the gold he has been saving up over the years, Nev and Crazy Keith decide they want to find the gold for themselves. They locate it hidden in a teapot in the ice cream van but a magpie flies away with it. At a surprise farewell party for the caretaker Nev has to admit what has happened but Mr. Prank has a surprise of his own in store.
