Not only did Lil' D fail the history test but we learn that Sunny did as well. Both of them re-take the test and only Lil' D passes. Meanwhile the heat is really getting to Kam. As it gets hotter and hotter he starts seeing things that are not what they really are. Kam after finally getting into a river with the rest of the class wants more cool water so we see him destroy the dam with a sledgehammer. As the water gushes though the breach in the dam Sunny builds a canal, aqueduct, and a moat to protect the school. When he finishes the history teacher gives Sunny an A+ for the test and Sunny also saves the school.
