It's Halloween and Billy can't wait for the village Halloween Party. There's just one problem ... his Mini Monsters are at the party too! Sparkle-Bogey's in the apple bobbing, Trumpet's in a pumpkin and Gloop's playing 'Guess the Body Part'. Can Billy find his monsters before anyone else does?
Billy hates swimming. It's cold and wet and horrible. And just when Billy thinks things can't get any worse, his pet Mini Monsters turn up at his swimming lesson and make one very big SPLASH...
