Blue

Unaware Giantess Loryelle steps on shrunken employees of a cleaning company
An accident occurs in a research institute, when an unknown cloud of colored smoke is set free. The employees of a cleaning company, who work there, get shrunken and teleported into my hotel room.
Unfortunately, there is a report about some biting blue bugs on the radio and the little men in their blue overalls just look like those biting little bugs to me.
