Putana

Vinata and the group of mothers come to Skanda, asking to be his mothers and to devour the offspring of other mothers. Skanda grants them motherhood but redirects their hunger: he allows them to afflict children up to sixteen years of age, and from his own body springs a being that becomes the graha Skandapasmara — the first of eighteen terrible seizers.

Ravana's followers—pishachas and rakshasas—attack the monkey army while remaining invisible. But Vibhishana knows their trick and strips their concealment away. The monkeys see them clearly, and the ambushers become the ambushed.
