Olive Oyl asks Popeye how the mirror was broken. He tells her that Swee' Pea was wondering what was inside the mirror so he walked through it and found himself in a meadow. Swee' Pea fell into a hole and found himself in a small house. He ate some pills and grew very tall. Then he ate a different pill and returned to normal size. Outside, he found a garden where Queen Sea Hag and King Brutus were playing croquet, using Jeeps for balls and vultures for mallets. He refused to play so the Queen ordered him killed. He escaped through the mirror. To prove that Swee' Pea could not possibly have gone through the mirror, Popeye crashes into it and it breaks.
