A downthrow is a type of cap throw that allows the player to throw Cappy downwards. If Cappy hits the ground before extending fully, he will move continue forwards along the ground. Downthrows are often used in trickjumping as part of an up-down vault.

Execution

There are two methods for executing a downthrow. The first method consists of performing a ground pound followed by performing a cap throw by shaking the controller downwards or pressing X/Y after releasing the ground pound button. If the ground pound button is not released before the cap throw is performed, Mario will initiate a roll instead of a downthrow.

The second method for executing a downthrow requires the use of a pair of Joy-Cons. It consists of shaking the controller downwards, which will cause a regular motion-controlled cap throw if done without using a pair of Joy-Cons.
