Herman loves to entertain his Street Monster pals at Sarah's Cafe, making their favourite hot beverage - the DOUBLE TROUBLE CHOCOLATE BUBBLE VANILLA TRUFFLE MOCCACHINO with SPRINKLES! But they soon notice that all is not well with Herman. Spooky sounds coming from the attic have been keeping him up at night, and his drinks aren't as delicious these days! Could it be the mythical Attic Monster keeping him up at night? The only way to find out is for Herman and his little pal Carpet to go up to the attic and face their fears!
