Hello and welcome to What is What. This is a sea trip on the legendary Titanic. Why is this ship so famous? Why did only three out of four chimneys smoke? How did the passengers waste their time in the first class? What was there to eat on board? How was the ship powered? Why was the ship considered unsinkable? And what about the iceberg? You already know Theo, Tess and Quentin. When it comes to discovering our exciting world, they are at the forefront. The three have their eyes and ears everywhere and are constantly on adventurous discoveries. Yes, adventure and action. Exactly the right thing for me. Tess, our red exclamation mark, is very brave. A real go-getter. She would love to become a pop star. La la la laaa! Have mercy, Tess! You'll lose your ears in a year! Theo, the blue question mark, is not entirely convinced of the musical qualities of his girlfriend. He prefers to explore all sorts of things and seems to know everything. Yes, um... Scientific studies have shown that... That what? That it's about to start. Stop! We must not forget Quentin. The yellow exclamation mark loves to joke and jumps and rolls around his two friends. And best of all, he can turn into anything.
