A large bee that can be heard from yards away that flies toward you in a drunken manner.
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.
"Watch out for that rumbletumbler, it's all shit-faced and flying right at you."
