*During this section, you only have to memorize one sequence.*

Guess what? Because all 4 of the top corners are on the top layer by now, then all 4 bottom corners are already forced on the bottom layer, where they belong anyway. And as we all know by now, the bottom side is **green**.

**Q: **Who lives in a pineapple under the sea?

**A: **SPONGEBOB SQUAREPANTS!

Because all 4 bottom corners are already forced on the bottom layer, all we have to do is shift them around to their correct places. The bottoms of all 4 corners are green, but what about their sides? At this point, there are 3 possibilities:

- No side has matching colors
- Only 1 side has matching colors
- All 4 sides have matching colors

Now that we know the status of the bottom corners, it is time to fix them. Of course, if all 4 sides have matching colors, then the bottom corners are already solved.

SET UP: |
Do the Move: |
Result: |

None |
Desc. notation:## b- R t+3 R |
The bottom corners have one side with matched colors, but the top layer is temporarily scrambled. To fix both layers, we must do another step... |

Now, rotate the bottom layer until the two matching sides are on the left: |
Desc. notation:## b- R t+3 R |
All 4 sides of the bottom layer match; the top and bottom corners are solved. |

SET UP: |
Do the Move: |
Result: |

Rotate the bottom layer until the two matching sides are on the back: |
Desc. notation:## b- R t+3 R |
The bottom corners still have one side with matched colors, while the top layer becomes temporarily scrambled. To fix both layers, we must do another step... |

Now, rotate the bottom layer until the two matching sides are on the left: |
Desc. notation:## b- R t+3 R |
All 4 sides of the bottom layer match; the top and bottom corners are solved. |

The bottom corners are already solved! Now you can proceed to solve the Top Edges |

In case you haven't noticed, the same sequence was used throughout this entire section; so just in case you are curious, here's what really happens:

Desc. notation: | It swaps two opposite corners on the top layer, while swapping the two adjacent right-side corners on the bottom layer. | |||

## b- R t+3 R |
||||

JS notation: | ||||

## (0,-1)/(3,0)/ |

You must always perform this sequence twice. As you solve the bottom corners, the top corners become scrambled after the first time, and then unscrambled after the second time. After the smoke clears, the bottom corners are finshed as well.
