Fish Clip
Fish Clip, also known as Seaside Boundary Manipulation, is a trick in the Seaside Kingdom that is used in numerous speedrunning categories. This trick involves abusing the physics of the ocean boundary with a Cheep Cheep to clip out of bounds. The boundary acts as more of a force field than a barrier, slowly pushing Mario backwards when he gets near, and it exhibits some strange behavior when Mario exits a capture near it. This trick is often recommended even to beginner speedrunners, since it is relatively simple to perform.
Reproduction steps
To perform Fish Clip:
- Capture a Cheep Cheep and bring it near a small notch in the kingdom boundary (pictured at right);
- Swim straight at the notch, moving roughly perpendicular to the boundary;
- Just as the Cheep Cheep stalls and is about to be pushed backward by the boundary, uncapture it;
- Swim a bit away from the boundary as Mario;
- Throw Cappy back toward the Cheep Cheep and home in to recapture it;
- Swim downward immediately.
If the steps were executed correctly, the Cheep Cheep should clip out of bounds below the ocean floor.
