An unusual guest stopped by Washington’s Semiahmoo Resort Thursday night when a juvenile harbour porpoise became stranded on a nearby beach.

Guests noticed that a struggling porpoise had strayed too close to the shore, and notified staff.

Semiahmoo Resort employees Ken Lord, an engineer, and landscaper Ron Kruse raced to the beach to try and free the porpoise.

Video captured at the scene shows the two men working to free the animal, while the porpoise flips its tail back and forth.

Marine Animal Rescue and Animal Control told the men to keep the little porpoise wet and breathing as they worked, and before long the porpoise was happily swimming away.

This isn’t the first marine animal rescued by humans on the West Coast this week.

Rescue workers in Hartley Bay, B.C. kept an orca alive for nearly seven hours after it became stranded on sharp rocks during low tide on Wednesday.

The volunteers erupted in cheers when the stranded orca eventually managed to swim free.
