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 Trashland, a whole world full of different types of small slimy monsters who all live peacefully alongside each other - at least until now . . . When the hideous Countess Kiss and her vile mouth monsters invade the Mouth Museum and steal all the teeth, the Slime Squad are rightly suspicious. It's time to fight crime with slime!
