Ok everyone, this is not usefull in the least, just if you wanna brag to people about how you are still big and orange (kinda like the way ima typing) First of all, you need at least the walking speed magical riding broom, and second of all, you need at least 2 pumpik treat things.
Heres what you do:
Eat a pumpkin or eat pumpkins untill you get the glow and grow bigger.
Keep eating again, until you are a ghost that floats in the sky (If it is not your second pumpkin, it may not work, i haven't tested it.)
While the ghost, mount your broom, then dismount.
While dismounted, you will be still be huge and orange, but no longer the floaty ghost.
Have fun, and
PS: There you go. I hope that image is better for all you flamers out there.
