We know a tiny bit more about the story being told on the new Sesame Street themed dark ride coming to PortAventura thanks to a tweet. The promotional tweet shows off a graphic for the new ride and a description in English that mentions “Detective Grover in going on a secret mission. To carry it out, he will need help from some brave families that are willing to embark on a million and one adventures as they travel through the world of Sesame Street!”.
