Trap the puppy between an object and a slippery slope. After a moment, jump in the direction you want to go for a huge speed boost.
The puppy normally gains speed while sliding down a slippery slope. While you're stuck levitating on the slope, you continue to gain speed. Jumping releases it all at once.
The only useful levitation boost is currently the Spooky Forest levitation boost.
The Royal Museum levitation boost is only used in the TAS, and the Lumber Mill log boost above isn't used anywhere.
