In "adventures of isabel", the only one of isabel's enemies who survives is?

The doctor was the only enemy of Isabel that survived in the poem. When she met him, he seemed to be troubled and offered her pills. Despite the medications and treatments, Isabel did not get scared nor did she scream instead she remained positive and treated the doctor with the use of her attitude. The other 2 enemies that did not survive were the witch (that she turned into milk) and the giant (that Isabel bravely face by cutting its head).
