Rosa is given a chocolate machine working on Pin's on perpetual motion as a birthday gift. The machine can produce chocolate in any quantity. The next day, Rosa takes advantage of this device to get loads of chocolate. Krash and Chiko, passing by, ask her if she'd get sick from eating that much, to which she replies that she'll always feel good and plans to make the entire world out of chocolate. With that in mind, she sets the machine to the limit, flooding the entire valley with chocolate.
Trapped in chocolate chips, Krash, Chiko, Wally, Carlin, Olga, Dokko, and Barry start digging tunnels until they eventually meet each other. Chocolate slowly melts in the sun and starts flooding the tunnels. Barry manages to find a hole in the ceiling, but it is high to reach. KikoRiki are completely desperate, but Pin comes to their aid on a balloon. The crew starts looking for Rosa, and soon find her swimming on the bucket in the middle of an chocolate sea. After being saved, Rosa starts hiccuping and realises that she ate too much chocolate. Carlin tells her that it's all about moderation.
