During a drought in Plainsville, Penny and Rudy try to find refuge in Chalkzone. They try to enter in an old quarry, which happens to be in the bottom of the Wait 'n Sea in Chalkzone. Chalk water starts filling up in the quarry, and Rudy and Penny go to the rainmaker to bring rain and wash the chalk water away. In the meantime, several adults who are splashed by water magically obtain the minds of children and playfully swim in the rising chalk water.
