Weird B is a glitch which allows you to use B Button Action IDs as if they were Item IDs. Weird B occurs when a transformation has a an Blank B button. Many masks put special actions on the B Button, such as Punch, March, Dance, Pound, and Dive. When you perform Weird B, you will use an item which has the same value as the B Button Action. The resulting item is different on the US and JP versions.
|B Button Action
|Blank (Goron Spike Roll)
|Punch (Goron, Zora)
|Land Title Deed
Save at an Owl Statue on Epona, then reload the save and put on a transformation mask. Get off Epona for Weird B. This was the original Weird B method.
In order to use the Weird B values below, the transformation you are using must already have an blank B button using one of the methods above.
After Goron Link has an blank B button, press B on the first frame of uncurling to drink Chateau Romani or Obaba's Drink, depending on the version of the game you are on.
After Zora Link has an blank B button, simply press B on the first frame you land underwater after pressing B to dive as Zora to pull a bombchu. It also works on the first frame you reach shore. This is shown in the video above.
Weird B can be used with 0th Day to get a bottle on human B.
