Every day was the same, spent harvesting the particles that collect in the fresh dust in the fields under the couch.
Until one day, the homeowner’s new robot vacuum cleaner arrives.
Because of that Harriet’s best friend and everyone else living under the couch is sucked up by the vacuum.
Because of that she must travel through the house to save them.
Because of that Harriet is confronted by the house cat.
Until finally she tricks the house cat into pouncing on the vacuum to free her friend and everyone else.
And ever since then Harriet and her best friend are always at other’s side.
