Here my guess:

Since Logan will have the Golden Play Button in the movie, it could be about Mario reclaiming his stolen Play Button which is in a mountain hideout (based off the fact that there's a mountain behind the characters in the thumbnail ) that's owned by the villain, and the SML Heroes find it after searching all over the US, including a desert area (because Logan said he filmed in the Sahara.) and the Villain is Principl Steinback who's plan is to kill Jeffy and Junior  who are on the look for the Play Button  with missiles (Probably the causes of the explosion in the thumbnail) and he is also in love with Peach who plans on killing Mario.
