Entry 31 (MJ and the Black Fish) I have to admit that I totally missed the reference until I saw the car rolling down the hill and I said: "Of course!" Beside my lack of pop culture knowledge, this team completed the course in record time and manage to smash against the ramp's Plexiglas during the last turn.
Entry 33 (Downhill Jerkies) had the blessing of Mr. Oberto himself but their speedboat could not get up to speed in the dry land.
Entry 35 (Runaway Bride) had a lot of good points in its favor: a great vehicle, a good driver and a marching band.
Entry 36 (Ohana Belltown) (just a block from our apartment) gave a decent performance but part of the vehicle was lost after the last turn.
