The Umbrella Boost takes the form of Big's umbrella, except this one has a green and red-striped screen and a red and white candy cane for a pole.
In gameplay, the Festive Umbrella Boost can only be obtained at random from Item Boxes by Santa Big.
When used, the user pulls out their umbrella and opens it up in front if them, causing it to catch the wind coming in from behind and carry the user forward at high speed. In gameplay, this greatly increases the speed of the user for a short time and allows them to damage enemies and opponents on contact, resulting in the latter losing Rings and being slowed down slightly. Also, when a character is upgraded to level 2, 8 and 14, the Festive Umbrella Boost will last longer.
