Fish Clip

File:SMO Speedrun Tutorial - New Seaside Out of Bounds Route

Fish Clip, also known as Seaside Boundary Manipulation, is a trick in the Seaside Kingdom that is used in numerous speedrunning categories. This glitch was discovered by syrkl and 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, and only Mario, backwards when he gets near. Leaving a capturable enemy past the start of the force field will reset any momentum Mario had and will allow Mario to go farther.

This trick is often recommended even to beginner speedrunners, since it is relatively simple to perform.

Execution

To perform Fish Clip:

• Capture a Cheep Cheep and bring it near a small notch in the kingdom boundary near the Bubblaine Northern Reaches moon (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.

Speedrun usage

Any%

In the Any% category, Fish Clip is performed just after collecting the Bubblaine Northern Reaches moon. After performing the clip, the Gap in the Ocean Trench moon is collected from half-bounds by shaking the controller to perform a spin attack. The loading zone to the Sphynx's vault can then be entered from out of bounds, allowing the moon inside to be collected. This route replaces the previous route, which utilized Rocket Flower Refresh to collect the notes moon earlier in the route, instead of the moon from the Sphynx's vault.
