How does darzee's chant make Rikki tikki tavi into a superhero?

Darzee's Chant (see below) embellishes Rikki-Tikkis accomplishments and phrases like "Rikki the valiant and true, Tikki with eyeballs of flame" give him "super powers"

Singer and tailor am I --

Doubled the joys that I know --

Proud of my lilt through the sky,

Proud of the house that I sew --

Over and under, so weave I my music -- so weave I the

house that I sew. Sing to your fledglings again,

Mother, oh lift up your head!

Evil that plagued us is slain,

Death in the garden lies dead.

Terror that hid in the roses is impotent -- flung on the

dung-hill and dead! Who hath delivered us, who?

Tell me his nest and his name.

Rikki, the valiant, the true,

Tikki, with eyeballs of flame,

Rik-tikki-tikki, the ivory-fanged, the hunter with eye-

balls of flame. Give him the Thanks of the birds,

Bowing with tail-feathers spread!

Praise him with nightingale-Words --

Nay, I will praise him instead.

Hear! I will sing you the praise of the bottle-tailed

Rikki, with eyeballs of red!
