Angry bats cry Death Eternal! Fangs glisten, hungry. Instinct joins kill, laughing. Murder; no obituaries. Predators’ quietus, rapacious screams. Thundering ululations, venomous wings. Xenophobic, yet zealous.
Obituary: A published notice of death.
Quietus: Death. Release from life.
Rapacious: Subsisting on live prey. Predatory.
Ululation: To howl, wail, or lament loudly.
Xenophobic: Fear or hatred of strangers.
Zealous: With great enthusiasm.
See? My vocab paid off for something.
