And I'm Possum.
Did you see that big kick?
It landed here.
I'm going to get it.
I'll have to be careful going into the garden.
I don't want to damage anything.
Hop, hop, hop, hop, hop.
Finally the rain has stopped.
Possum was very keen to go outside and play.
While he's been out there, I've been making lunch.
We're going to have some wraps for lunch today with some lovely salad in there.
It's almost lunchtime.
Did you have fun playing outside?
Oh yes, I really enjoyed myself.
Did you get wet?
I'm nice and dry.
Ooh, and Sally, I'm so good at kicking my soccer ball.
It went so high.
Oh, that's great!
I've got everything ready for lunch now.
We can have some wraps, ok?
If you'd like a drink of milk, you can go to the fridge and get it.
Ok, I'll get it.
Ooh, it looks delicious.
Well, you need your wrap first and then put the things on it that you'd like.
What is it Possum?
Sally, something very strange has happened.
What were you just doing Sally?
Well, you were outside playing and I was in here getting everything ready for lunch.
Did you stay in the kitchen the whole time, or did you go somewhere else?
Well, I did leave the kitchen just to go and get some tea towels, but most of the time I was in here.
This is very strange.
What is is Possum?
Look at the muddy footprints!
Well, somebody has obviously come in from outside.
I'm sure you all know where the muddy footprints come from.
This is a case for Police Officer Possum!
Come on, over here.
Can you please walk along these footprints so I can see?
Right, left, right, left.
That's how I normally walk.
You're right, Sally.
You went left, right, left, right.
I know what I need to do.
I need to copy these footprints into my book.
Possum, it'll be very hard to solve the case.
This is such a small picture compared to the big footprint.
They're different sizes.
You're right Sally.
You're very clever.
You could become a police officer too!
Well, I'll need a bigger piece of paper.
Then I can cut out a stencil.
Well, I've got some big pieces of paper in my craft box.
I'll get some for you.
They're the same.
I, Police Officer Possum, am very clever.
Can you please place your right foot on the stencil?
This is a very hard case to solve, this one.
Have you measured other people's feet to see if it's the right size or not?
Good question Sally.
I have not done that yet.
Well, it was a great idea to stencil the footprint, though it's not exactly the same size, is it?
It's going to make it very hard to solve the mystery.
Why don't we watch some children making shapes in a different way?
Maybe that will give me an idea.
Oh, that was great!
It was so good.
Did you see those children using the plaster of Paris?
That was the white stuff they were playing with.
I've actually got some in my craft box.
Um, Possum, when you were outside, you didn't see anybody in the garden, did you?
No, I didn't but why don't we go outside and see if there is a mystery person out there?
Ok, let's go.
Oh, hold on.
Come on Sally.
Maybe along here.
Oh, thank you.
Thank you so much.
That was a delicious cottage pie.
I really enjoyed it.
Oh, I love sharing food.
You might see Possum acting a bit strange.
He's trying to solve a very serious mystery.
He's trying to work something out.
Amanda, were you here earlier today?
No, Sally gave that to me yesterday.
The muddy footprint wasn't here yesterday.
Step on that please.
It's not Amanda.
I can't stay and help you solve the mystery.
I have to go work.
Whose footprint is it Sally?
I don't know.
Come on, then.
Wait there. I'll be right back.
Wait her, Sally.
You put your foot on that.
Oh, that for me?
Here you go Sally.
Oh thank you.
It's wet and now there's a muddy footprint.
Yes, so it's the same one as the one in the kitchen.
It's from here!
Yes, you're right.
Ooh, I need my stencil.
Can you get it for me, please?
Oh, of course.
This one's hollow and this one's flat.
It doesn't fit!
Ooh, do you remember watching the children making those lovely shapes?
You see, this is hollow.
That means we can use plaster of Paris and pour it in.
Then once it sets we can take it out.
That means when it's dry I can take it out, and if a visitor comes, I can see if their foot is the same size or not.
Yes, that's right.
Can you go get it for me please?
Great stuff Sally.
This is how we make our plaster of Paris.
I've got water in the bucket and I've got a little bit left over as well in the jug.
We have to be very careful though.
The plaster of Paris is in powder form and as I tip it in, you need to stir the water in the bucket.
Be careful not to splash it, though.
We can't stir it too long or else it will set.
So once it's mixed properly, we'll pour it in.
Ok, I'll stir.
Here we go.
Could you pass the wooden spoon?
It's starting to thicken up.
Oh, that's great.
Oh, yes, that's good.
This will take some time to set, so while we're waiting, why don't we go and play some soccer?
I was worried that the soccer ball might land on our plaster and splash it everywhere but it hasn't.
Good, and it looks like it has set.
Would you like to lift it out?
Doesn't that look good!
Look at all that detail.
It's so lovely.
The ball…and my foot…and…
I've solved it.
The ball landed in the garden earlier and I put my foot in there to get the ball back.
I've been trying to solve the mystery of who it was and it was me all along!
Well, you did such a good job being Police Officer Possum and investigating who it was, and now you've solved the mystery.
It was you all along.
Why don't we go into the kitchen and you can clean up your muddy footprints?
I can do that.
Well, our time is up.
Thanks for watching.
See you next time.
Did Sally make those muddy footprints in the kitchen? Well, who did? This looks like another case for Police Officer Possum and what a clever way he has to find out who made them.
