Yo and Jennifer taste different types of fruit. Some fruits are sweet and some are sour. Cucumbers aren't sweet or sour. Jennifer doesn't like green food, and Yo only likes red food, like tomatoes and strawberries. Yo says yellow is a sour color and lemons and grapefruit are sour, too. Yo's mom lets Jennifer try pineapples. Will Jennifer like pineapples? What kind of fruit will they try next?
