Kolam was an otter of Brogalaw's holt. He was part of a group of otters (including Durvy and Spraydog) that his Skipper Brogalaw took with him to steal rope from the ships of the Blue Hordes. This rope was then used to rescue the hares imprisoned in Salamandastron by Ungatt Trunn. Spraydog was also one of the Seafaring Bark Crew. Since he was a minor character, nothing else is known about him.
