Investigation of the blue spots source: pump-room and freeze-bomb

What happened

During Plumbing class, Dash deduced the water fountain was the source of the blue spots since everyone who drank from it got spots except Gronville. Dash activated a freeze-bomb, freezing Mr. Plumtree and the class for fifteen minutes. He ran to investigate the fountain, then traced the water supply to the pump-room under Mr. Plumtree's classroom. There he found muddy footprints leading out the back door to a flowerbed at the school's outer wall, suggesting an intruder had entered via the wall.

Resolution

Dash found suspicious muddy footprints but ran out of time before identifying the intruder. He returned to class just as the freeze-bomb wore off.
