The Peas are maybe magic. Probably they mutated because of a crazy nuclear explosion. Maybe... maybe they are red because the ground was filled with villager's blood... from some battle... like in those bloody awesome animes I sometimes see based on old time japanese or chinese eras. And the plant drank the blood, and the peas are red now. Or maybe... maybe a pea plant and a strawberry one got together, loved each other very very much... and then one day... the red peas were born! Yai!
