Sea Bear attacks are preventable by drawing an Anti-Sea Bear Circle in the sand.
Though it's credited that Dee Bradley Baker voiced the Sea Bear, additional sounds were from archival recordings from Thurl Ravenscroft (original voice of Tony the Tiger), James MacDonald (former voice of Mickey Mouse), Clarence Nash (original voice of Donald Duck) and Candy Candido (misc. voices in Disney movies and attractions).
