|Sigrid and the Bumpers|
Sigrid and the Bumpers is the fifteenth episode of the fourth season.
Sigrid, the Supply Ship is convinced that she can do everything a tug does, and she does manage to free Digby when he gets stuck. But when she tries to tow Bedford Buoy, all she does is knock him out of place. She is sure that she could do it if she only had tugboat bumpers. But Shediac, the Shipyard Shed won't give bumpers to anyone who is not a tug. So Sigrid finds a different way to help Canso Colossus by using waves. Sigrid is delighted when she is rewarded for her help with her very own bright green bumper. But since she doesn't really need the bumper to help ships, she wears it proudly on her wheelhouse as a decoration.
