Swash was a female otter member of Skipper's crew. She was the sister of Blekker and wore a coat. After Deyna was taken to Rukky Garge, Swash left with her sister and 20 otters for Redwall Abbey to bring news to Mhera and Filorn about Deyna. They then remained at Redwall as a precaution against a possible threat from the Juska.
