Two strange maggots, Red and yellow, live under the grill of a sewer drain where people pay little attention. In the secret place, they relish the things that people throw into the sewer, like chewed up bubble gum, melted ice cream, coins, you name it.
The two characters sometimes get into trouble, happy and quarrel over possession of these things. Also, simple matters to humans like rain, midday heat, mosquitoes and flies can bring them big troubles.
