Anansi proposes that they put their loads together, sees that Tumble-bug's is at the bottom, and makes the ruling in order that he may get the butter and Tumble-bug the lard. Compare number 46 and the opening episode of the last number.
The revenge story is recent. In Wona, Tumble-bug suffers further at Anansi's hands.
In Tremearne, FL 21:213-214, Tortoise and Spider have a bull in common; Tortoise eats the liver and Spider claims in compensation the whole bull. Tortoise pretends dead and frightens Spider, who thinks it is a spirit and gives him everything.
