The elephant cannot get up if it falls, so it sleeps leaning on a tree. Hunters cut part way through the tree so when the elephant leans on it, it falls.

This is one of the most commonly described characteristics of the elephant, told in many other texts.

When the hedgehog senses that it is the season when grapes are ripe, it goes to the vineyard like a thief, climbs the best vine, and causes it to break and fall to the ground. The hedgehog then rolls around on the fallen grapes so they stick to its spines, and thus carries them home.

This is the standard story of the hedgehog, except for the breaking of the vine to get the grapes. In other accounts the hedgehog just knocks the grapes off the vine.

The lamia has poisonous milk, so that she kills her young while feeding them.

When the crow sees its chicks hatch with white feathers, it will not feed or care for them. Later when their feathers turn black, the crow can recognize them as its children and so repents of its negligence.

This is part of the standard description of the crow.

The asp is the guardian of a tree that produces balm. To get the balm, an enchanter sings to the asp and puts it to sleep. Then the balm can be safely gathered.

Tiro is an unusual name for the asp, and no mention is made of the asp blocking its ears, but other than that this is the most common description of the asp.
