Marco Moves In - A grizzly bear walked all the way from the zoo to my front door and not a single person noticed him. I suppose it helped that it was night and that he was wearing a big black duffle coat with an enormous hood that covered his hairy head. He knocked on the front door three times, loud knocks that shook the house. Patrick makes his unexpected guest at home, while keeping him hidden from the neighbours, police and his very distracted mum!

Marco: Master of Disguise - Nearly everyone in my class had a pet of some sort. Lots of them had dogs and a fair few had cats, budgies and goldfish. Max Wallace had a hamster, and Adam O'Hara had a tortoise, which he claimed was 60 years old, though I'm pretty sure he was exaggerating. Sam Tripp had a small lizard and a pet rabbit, which was a strange combination. But no one I knew had a grizzly bear sleeping in their garden shed, or sat beside a grizzly bear most nights watching TV.

Marco: Moonwalker - After escaping from the zoo and coming to live with Patrick and his mum, Marco proves to have many talents. Now Patrick discovers that Marco is also a musical genius - he can play the trombone, banjo and even moonwalk like Michael Jackson! ‘Let’s start a band’, Patrick says, and Marco becomes a star. Then disaster strikes. He is spotted without his mask and taken back to the zoo. How will Patrick and Mum get him out again?
