The Hoobs are here to find out all about Peeps and Tiddlypeeps, which makes them wonder how Tiddlypeeps find things out. Along the way they also discover how many hoobnips fit in a tart tin, how to give Roma the Hoobyhics and how much fun you can have with something soft and squidgy. By the time they get to Hoob News one thing they've found out is just how much there is to find out!

The Hoobs would like to give a monkey something to make him happy - but what? It seems that a monkey already has everything they try. Only when they've finally found out and they go back to their monkey book does it turns out that the answer was right there in front of them all along!

Groove thinks there can't be a better way of saying hello than giving his tail a good old wagga-wagga - it's almost as good as a Hoobledigger! But how do the Tiddlypeeps say hello to their friends when they're really pleased to see them? They find out how Queens say hello and Roma even says hello to some rugby players but in the end the Tiddlypeeps teach them the nicest hello of all!

Nothing makes a Hoob laugh like a hoobledangler. And Tiddlypeeps laugh at all sorts of strange things but they don't don't find hoobledanglers funny at all. So what would make a Hoob AND a Tiddlypeep laugh? The Hoobs try to laugh at things in crackers, things you sit on and Peeps who fall over. But in the end it's something much simpler that's funny enough to make Groove drop his plank!

Stars are just about Iver's favourite things - along with questions for Hoob News! Roma tells them about a star they can see in the daytime and the Tiddlypeeps show them how they can make one. But when Hubba Hubba sends them a story from Hoobnet, the Hoobs find out just what it is that really makes a star a star!

Groove wants someone to keep him company while he's out collecting. Maybe an animal would be the best thing - but what kind?

How can Tula get Groove and Ivers' attention when they're playing Hooby Run N Yell? By finding something louder than their yelling - that's how!

The Hoobs miss floating on the water in a Hooblebobber. There aren't any Hooblebobbers on the Peep planet but maybe they can find something that floats in just the same way.

There's a dog outside the Hoobmobile. But why does it keep barking? Maybe it wants a hoobledigger!

Groove doesn't fancy the idea of running - too much effort! But what happens if the Hoobmobile goes off without him - he'll have to catch it up somehow!

Something's wrong with Iver - first he's hot, then he's cold and his nose is making a very strange sound indeed! Maybe the Tiddlypeeps will know the answer.

The Hoobs are very impressed by how high frogs can jump. But how do they do it? Perhaps it's all those flies they've been eating!

Iver's lost his hoobtoobe and can't find it anywhere. But every solution the Hoobs find seems to be about helping you not to lose it in the first place!

There's nothing like a Hoobyhidey for hiding behind. The Peeps seem to have Hoobyhideys too. But they don't use them for hiding... so what do Peeps use Hoobyhideys for?

Groove's tree has lost all it's leaves. Will they ever grow back? And why did they fall off in the first place?

The Hoobs have run out of Hoobygoop. What do the Peeps have that they can use instead? And more importantly - who makes it?

The hoobytug is broken. And you can't have a good pull with a broken hoobytug. There must be something on the Peep planet the Hoobs can use to fix it - but what?

A Hoobs home is his Hoobmobile. It's hoobacious - you can live in it and take it around with you wherever you go. But what other animal has a home like that?

From me to you - Hoo Hoo Hoo Hoob. From you to me - Hoo Hoo Hooby. But why do Tiddlypeeps give each other presents?

Tula's having a bad hoobyfur day. Hoobyfur is hoobelly groobelly but sometimes you just want it to do something else. What can Tula do to make hers more exciting?

Nothing makes a Hoob's Hoobypaws feel as hoobacious as the clapping in a Hoobledoop Whoop. But do Tiddlypeeps clap their hands in the same way?

What can Tula wear to smell nice for a Tiddlypeep party? Cheese of course. Or something that smells of cheese. Or maybe not.

These Peep things called combs are perfect for keeping Hoobycookies in. But is that what the Peeps use them for?

There's nothing better than a good Hooblegaze. But it gets a bit chilly here on the Peep planet. So how can the Hoobs keep warm while they're Hooblegazing?

There's nothing a Hoob hates more than getting wet. But there must be some reason why all this water keeps falling out of the sky.

Groove's collection of things that move is Hoobygroovy. He's got things that shake, things that shudder and things that spin. But it won't be complete until he finds something that wobbles.

What do you do when you've ruined Groove's best ever painting of an "Icecream-asaurus?" And how do you stop him finding out before you've made it right?

The Peep planet is absolutely covered in sand. Sand on the beach, sand in the desert, sand everywhere. But what's it for?

Something's keeping the Hoobs awake. And if a Hoob can't sleep, a Hoob can't answer questions. Questions like 'What's all that hooting at night'.

If a Hoob can't find their Hoobarama, then a Hoob can't play Hoobarama. Is there anything soft, round and flat on the Peep planet that they can use instead?

Everyone knows that Hoobs hate getting wet. But what if they didn't? And if they didn't, could they live underwater like a fish?

There seem to be hoobloads of things on the Peep planet that open with keys. But what if you've got a key and you don't know what it opens.

There are some things you just have to wait for, like Hooboblubbers. But until your Hooboblubbers have set, what do you do while you're waiting?

Groove has had a spillage. There's a big puddle of Hoobjuice on the floor of the Hoobmobile. So how can the Hoobs keep their hoobypaws dry?

A fly is small enough to fly inside the Hoobmobile. But Groove can't keep a fly in his collection. What can he have instead?

The best time to twizzle your twizzletuft is at Hooby twizzletuft time - of course. But when's the best time to visit the Tiddlypeeps?

Iver can't sleep so Tula and Groove try to find a way to help him drop off.

Groove's got a beautiful potato plant. Just one problem - it doesn't seem to have any potatoes on it.

Something's eating the Hoobmobile - a mouse. What can the Hoobs give it to eat instead before their home gets gobbled up completely?

Teeth are usually found in mouths - not in old bits of boat. But where has this tooth stuck in a bit of wood that Groove's found come from? And what are teeth for anyway?
