A new trick has been discovered from a TAS created by Prosmasher64 on YouTube, and published on June 26th, 2021

This trick is known as the Inverted Grapple.

This is an example of what it looks like and how it's performed. A player must turbo, and while in Turbo mode, hold down on the analog stick, and simultaneously press A and B. This will allow the ball to launch.

The specifications of this trick are unknown, or how the mechanics actually work. But a video example is provided and will be updated as time goes on.

Here is a Nintendo 64 attempt with input display.
