In this video I show that you can collect both the red coins star and blue coins star in one go. This frame-perfect trick saves just under 40 seconds, bringing the best possible time down to just over 7:30. EDIT: I just found a new timesave that saves about 12 seconds. You do 100+Koopa+King as normal, but you don't manipulate King Bob-Omb's position, instead you go straight for Koopa the Quick. The moment King Bob-Omb explodes, you click to start the race. The stars will be separated, but you can use a glitch similar to this in order to get both stars anyway. Sub-7:20 hype???

@ILOVESMB Could I use this glitch for the Red Coin Individual Level? The fade into darkness starts before I collect the star so would I stop the timer before I even collect the star?
