Serafin og Plym

 A couple of days ago I rediscovered my favourite book as a kid, which I thought was long thrown away. It's the story of Serafin and Plym, 

two friends who were good at making things 

I guess the things they made were not so popular so they had to go from job to job

 

one day they decide to make a fantastic machine, that makes the most amazing fences ever
 

They celebrated the making of the machine, but when they tested it in the city, officials freak out, and Serafin and Plym got kicked out

So they decided to fence everybody in, then fence themselves in around hole in the ground

opening the sewer cover, they set off in an underground maze of caves, 

and they lived happily ever after,

 together.
