Cruise boosting (CB for short) is an exploit useful in BFBB speedruns. It can be triggered by using Bubble Bowl and Cruise Bubble on the same frame while on a flat surface. A faster and more useful CB can be done by then strafing left/right against an object to capture the walking speed into the cruise boost.
Cruise boosting works because the the Cruise Bubble cancels the bubble bowl, which causes it to not end properly. This causes the game to continue pushing SpongeBob forward as if he was still in the bubble bowl animation.
It can also be sort of performed in The SpongeBob Squarepants Movie, in one level, Welcome to Planktopolis... Minions. Jump on top of a the bungee hook, and you'll be spinning around and around. Use a Sponge-Bowl, and then walk off the bungee hook. You'll hear the windup noise and after you quit the bungee, you will see SpongeBob sliding across the ground, just like a cruise boost.
