Mrs. Levine and the STARfish find themselves in trouble again. It's the last day of August, and the kids of Rochester are bored. "Nothing ever happens in Rochester," complains Derrick, who will soon change his mind when an unexpected storm blows into town creating a whirlwind of trouble and activity. Reinaldo and his family, who are caught at the Rochester Public Market, are forced to take refuge at the home of the class bully. Mrs. Levine and Steven are stranded underwater at the parking garage of the Rundel Library. But lightning strikes the worst at the Seneca Park Zoo where an old oak tree falls, trapping a zookeeper and scattering the penguins. Rescue comes from an unexpected source.
