Herbaceous the Boy made of Cheese is back and this time it's Valentine's Day. Jimmy is so excited when he comes home from school. He has something wonderful to show Herbaceous....but, when he looks in his backpack it isn't there? His mom says he can't trace his steps and look for it because they have somewhere to be....so, Herbaceous and Cheesy set out to find what Jimmy lost. Can they get there in time?
