A member of the bear family who's footsteps sound almost exactly to that of a trunk with bump in it. The big bump bear is the natural predator to any other bear.
It was reported on June 3, 2003, that two teenagers in Pennsylvania scared away a grizzly bear by turning on their speakers to have bump in their trunk which then resembled the exact sound of a big bump bear which then scared away the grizzly bear.
