The Rumbling usually causes mass paranoia which paralyzes it's prey.
After the prey is subdued, it tumbles towards it in a circular motion to feast on it's kill.
Rumble Tumbler's are the "Lone Wolf" of the bee family, known for going rouge and slaughtering anything in it's path.
"I can feel the roar of the wild rumble tumbler"
