Goldfish, they're not just for kids  at least, that's what The Campbell's Company wants you to think with its recent rebrand. Instead of appealing to the typical kid of a consumer for the cheddar cracker, the Pepperidge Farm snack is going for a more sophisticated image with a (temporary) new name: Chilean Sea Bass. Though you may be imagining an entree at a sit-down restaurant when you hear that title, the cracker is the same as it always has been; the company is just hoping the new name can remind customers that the familiar snack is not only for their kiddos, but for them as well.RELATED STORY | 'We're baaaack': Is the nostalgic Lisa Frank brand making a return?"We know the love for Goldfish spans all ages. Chilean Sea Bass is a playful nod to adults that the iconic fish-shaped snack is for grown-up tastes too," Goldfish Vice President Danielle Brown said in a news release.If you're looking to get your hands on the grown-up snack, don't go looking in stores. Chilean Sea Bass crackers will only be available online  and only for one week. Starting Wednesday, a two-pack of the limited-edition snacks became available for $7.38, but they appear to be selling out of their daily allotment fast each morning.Not to worry, though: The company reminded customers that those wanting to chomp on the snack can just grab the regular Goldfish off the grocery shelves.
