Well kids, this is how it all began...

One day the smartlooking and ever polite British gentleman, Jon Burgerman ran into the semiconfused Dane, Sune Ehlers - on the net that is. I mean, they met, as this modern and information heavy society makes it easier and easier to do, on the wonderful world wide internet.
Since they don't teach Danish in English schools any more and since Sune tends to be rather incoherent in his communication, they began to speak in duudles. After a few years of meaningless duudling back and forth by email, the two inky beings got it into their heads that making doodles on paper and then forcing them on innocent children might be a good idea.
And so they made Hello Duudle 1

Difficult to understand but the mentioned piece of nonsense above somehow got sold out. And then, just when it seemed like all had returned to normality in the book business there they were again with Hello Duudle 2- The Duudleville Tales.

They also pester their surroundings with talks, stickers and what have you.
