Judy Moody and the Poop Picnic

Somehow Judy, Stink, and Aunt Opal end up at an abandoned amusement park, eating what...? (Age 5-8)
Judy is desperately trying to earn thrill points, so she plans a trip to the Cemetery Creep 'n' Crawl. Meanwhile, Stink has been collecting all the samples and evidence he can in his efforts to catch Bigfoot. Add in Aunt Opal's crazy driving (and bad sense of direction), and somehow they all end up at an abandoned amusement park, eating scat sandwiches. That's gotta be worth some thrill points. . . .
