The Festive Umbrella Boost's icon 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. It also has air currents swirling around it. In gameplay, the Festive Umbrella Boost becomes the user with the aforementioned umbrella opened up and spinning in front of them as a gust of wind pushes them forward from behind while the user leaves a colored aura trail behind them.
In gameplay, the Festive Umbrella Boost can only be obtained at random from Item Boxes by Santa Big.
Once obtained, the player can utilize the Festive Umbrella Boost by pressing its icon on the bottom of the HUD. When used, the Festive Umbrella Boost will increase the speed of the user for a short amount of time. The duration of the Festive Umbrella Boost is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Festive Umbrella Boost is in effect. In addition, any rival character who makes contact with the user while the Festive Umbrella Boost is in effect will take damage, causing them to lose Rings and slow down momentarily. It can similarly destroy any Badnik the user makes contact with.
The Festive Umbrella Boost can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the Festive Umbrella Boost will last longer.
