Bomb is female Creeper and she's ABSOLUTELY friendly-looking. Nicole never allows her to be angry or upset for a long time, she might blow up. But the others wants her to die because they think she's evil and ugly. Once they truly kill her (they made her mad, she blew up), Nicole is heartbroken and turns evil.
"I didn't land a single blow on your stupid Creeper! They just got TIRED of you!" - unknown hater to Nicole after Bomb's death
