An epic tale!

I want

to send my

chocolate… to the

WORLD!

You are

going to need

some boxes!

He made some chocolate…

… and he put it into boxes.

He put his chocolate on a truck.

Tim the boxes of chocolate on

trucks specialist.

He put his chocolate on a train.

Tom the boxes of chocolate on trains specialist

He put his chocolate on a boat.

Brad the boxes of chocolate on boats specialist

So his chocolate reached the world

(eventually)

But there was trouble in paradise.

Willy’s friends were really expensive.
