Fake Clippers
From ALttP Speedrunning Wiki
Fake Clippers is a technique to get through the Pool Room below Hammer Peg Lever without having the Flippers. This can be used in RMG and MG categories to access Hookshot early.
Technique
The first part of the trick involves getting Fake Flippers via Splash Deletion. This is typically done by pre-setting the Search Index earlier in the run (use 2 Lamps; direction doesn't matter), and then using 6 arrows and 2 bombs before jumping in the water to delete the Splash.
