Sniffy's secret tunnel discovered during Hole-Digging Class

What happened

During Hole-Digging Class, while Dash and Greta were digging their names underground in their Aardvark 66, they hit an uncharted freshly-dug tunnel not shown on the 3D macro-map. They followed it and found Mr. Sniffy's boreholicopter (license plate SNIFF-01) tunneling underground. Rebooting the macro-map to Mode-42F revealed Sniffy was tunneling straight to the Sniffsonian Museum. Time ran out and they returned to the surface.

Resolution

Dash and Greta returned to the surface without confronting Sniffy, having noted where his tunnel led.
