"That one was a little much, huh?" sighs Elspeth, scooping him up and ushering him into the nearest restroom.
There is nobody in the restroom. A square has them all cleaned up in a jiffy, and she offers him some water.
Hugs. Picking up and departing the restroom. "Now we have been on all the big roller coasters," she says.
"Well, let's give your tummy some time to settle and then we'll find a little one to try."
Hugs. Wandering around parts of the park that are not roller coasters for a while.
"Okay then." They find a relatively tame roller coaster themed around ladybugs. It is not big enough to accommodate adults; Harley gets his own ladybug and Elspeth stays behind.
Elspeth has already memorized the map. There are three more cute little-kid roller coasters, themed respectively around dragons, space, and flowers. Harley may ride them all.
