Lily and Fred live in London. London is a very big, busy city, full of buildings and traffic.

Lily and Fred are going on an adventure.

Their mummy and daddy are taking them on holiday to a foreign country, a country called France.

Lily and Fred help mummy and daddy pack their holiday things in the car and then they start their journey.

First they have to cross the sea to get to France.

They drive the car on to a ferry with lots of other cars and people.

When the ferry arrives in France they set off on the long drive to their holiday house.

Lily and Fred keep asking mummy and daddy if they’re nearly there.

Their holiday house is near the sea, on the edge of a pine forest and when they arrive, they love it.

Their holiday house is made of wood, it even has wooden shutters at the windows instead of curtains!

The days are hot and sunny. Lily and Fred, mummy and daddy are happy.

During their holiday Lily and Fred see new sights; lizards basking in the warmth of the sun, strange birds called Hoopoes and spikey plants called Palms.

During their holiday Lily and Fred do new things; they play bat and ball on the sand, cycle in the forest and eat their meals outside!

During their holiday Lily and Fred hear new sounds; pine cones splitting open in the heat to shed their seeds, the language the French people speak and the sound of the surf.

They also heard a mystery sound!

The evenings were warm, so mummy and daddy, Lily and Fred ate their dinner outside on the terrace.

That was where they first heard the mystery sound.

Every evening they heard the mystery sound.

They heard it so often Lily and Fred gave the sound a name, they called it Trevor.

It was a sound unlike anything they’d heard before.

It was like a croak, but louder with a squelchy echo. What could it be?

Daddy thought the sound was in the trees.

Mummy thought the sound was on the ground. Lily and Fred thought Trevor was in the spikey palms.

Daddy looked in the trees. Mummy looked on the ground. Lily and Fred looked carefully in the spikey palms.

Where could it be?

While they were looking they heard the mystery sound again.

A sound like a croak but louder and with a squelchy echo. Lily and Fred jumped up and down in excitement.

They said Trevor wasn’t in the trees or on the ground or in the spikey palms.

They said Trevor was in the drain pipe!

Daddy said the sound couldn’t be in the drain pipe.

Mummy said the sound couldn’t be in the drain pipe, but Lily and Fred were sure that’s where Trevor was.

So they all stood close to the drainpipe.

They stood very quietly and waited and listened.

The mystery sound was definitely in the drainpipe!

It was like a croak but it was louder and with a squelchy echo.

What could it be?

Just then it started to rain, soon it was raining quite heavily, so they stayed under the cover of the terrace to listen to the sound called Trevor.

They heard the rain fall into the gutter, they heard it trickle down the drainpipe.

They watched the rain come out at the bottom of the drain pipe.

Suddenly, there was a really quite small sound like a croak, not at all loud or with an echo and out from the bottom of the drain pipe jumped .............

........ a tiny tree-frog!

A bright green tree-frog. An almost luminous green tree-frog.

A beautiful tree-frog; called Trevor!

Trevor sat quietly watching them for a moment, then making a really quite small frog sort of sound, he jumped away into the forest.

Wasn’t Trevor clever to make such a mystery?

Clever Trevor!
