How the forget are you supposed to complete "Throwback Throwdown Speed Run"?!? You need all the 5 minutes to fight Bouldergeist and Major Burrows!!! Bouldergeist wastes my time because he never throws Bomb Boos. And, what's that middle planet between Bouldergeist and Fiery Dino Piranha for? There could have been a checkpoint there, but NO, it's just there to waste your time!!! And Fiery Dino Piranha NEVER deactivates his flame!!!
EDIT: I... DID IT!!!
