The Law o’ the Walrus

Coach’s nerves throbbed. He leapt out the sea & paddled over to the group, his eyes as cold as the water dripping from his whiskers, his fangs as sharp as an iceberg.

“All right, you shrimpy demands: ¡I want all o’ you to match up with a supply!”

They didn’t hesitate.

However, in their scramble to match together, some demands ended up with multiple supplies, & some supplies ended up with multiple demands.

“Whatever. It all evens out in total, a’least,” Coach grunted. “Come, you tube worms.”

He waddled down the arctic, his faithful supplies & demands boinging ’hind like a parade.

Prompt:

Coach, Nerve, Walrus
