From the Super Mario Wiki
The Swooper (known as the Swoop in the British English version) is an unlockable glider part in Mario Kart 7 and Mario Kart Tour. As its name states, the Swooper is shaped like the Swoop enemy. Just like the Paraglider, it offers an acceleration boost, while hindering weight, but like all the other gliders, it allows karts to go airborne for a brief time period.
