In order to trick The Leopard and tie him up for delivery to the sky, Anansi first digs a deep hole and sets a trap. Just try, I ask you, to think about how to show a spider with his eight tiny arms holding a device with which to dig a huge hole. Suspension of disbelief is called for when telling and illustrating these stories.
Anansi does manage to distract and trap the Leopard, then convinces him that if his tail is tied to a tree, Anansi can get him out of the trap.
