Why isn't there a racing game on my U.B Funkeys Speed Racer?

Someone help me I bought my son a speed racer funkeys we plugged it in and all we can play is funk gong and mask mayhem neither of which are very exciting. Also when I change from speed racer to the chimp nothing changes. My 6 yr old is going mental please help, he has a broken arm & can't do much else in this hot aussie weather.
