Sorry, @Shamu fans. The snarky persona of SeaWorld’s mascot will not be returning to Twitter after all. The irreverent account was suspended five years ago, after a whale killed trainer Dawn Brancheau at SeaWorld Orlando. Late Monday afternoon, though, some of @Shamu’s 10,000 followers got their hopes up when a tweet appeared, dissing Katy Perry and expressing the whale’s preference for Peter Frampton, Johnny Cash, Elvis and Bruce Springsteen.
