Ugh, the last autoscroll level (minus the Kamek autoscroll in 6-8). Luckily, the second half of the autoscroller can be skipped by using a perfect jump. A first-frame jump after landing on the ledge above the pink block will keep the camera scrolled down. This is useful because when landing normally the camera would scroll up and moving to the right load in the trigger for the autoscroller to start. But instead Yoshi can then just flutter past the flower and land on the downwards slope, avoiding the trigger that starts the autoscroller entirely. This saves ~25 seconds. Just watch the video if you have trouble understanding this explanation - it will be very obvious.
SUPER COOL ROCK BOOST
This saves about 1.5 seconds.
You can do the following to swag up your 6-5 for infinite swag points... and it's actually really easy to do as well!
TRUST THE SETUP!!!
1) You stand to the right side of the flame
2) You wait and jump at the right moment (Keep holding jump until your flutter is over) - DO NOT MOVE YET! (Do not touch your Dpad at all)
3) You wait until the pipe appears - That's the moment where you want to press JUMP and then LEFT and you keep holding both. You will do a flutter because of it, then headbonk, and do an automatic second flutter because of it (You want this to happen). You can just keep holding left until you are 100% sure to be safe.
