Mad scientist Godfrey Gunk had a dream - a dream of creating a whole safari park of monsters on an old rubbish dump. It didn't work. Little did Godfrey know that actually after he left the rubbish dump, his dream came true ... Meet the inhabitants of Landfillia, a whole world full of different types of slimey monsters who all live peacefully alongside each other - at least until now ... it's time for the fighting crime with slime to begin.
