We are in 3014.
Yes, you heard right: this adventure happens in the future. The Diplodocus is a BIIIIIIIG spaceship with the shape of a dinosaur. Bernard and Roger, also known as "the SUPERNYAPS" travel aboard the Diplodocus with their parents, who are members of the most famous rock band in theuniverse: Fart's soup.
In 3014, travelling through SPACE in a spaceship is as normal as it is to take a boat, a train or a plain nowadays. The only problem is that the inhabited planets are SOOOO FAR that sometimes it takes months to get there!
And meanwhile, unexpected things continue happening in the Diplodocus...
