Hammerhead Beach

From the Banjo-Kazooie Wiki, the largest Banjo-Kazooie info resource.

Hammerhead Beach was the beta name for Treasure Trove Cove in Banjo-Kazooie. It is commonly and widely thought to be one of the beta levels that Rare did not end up releasing. But in an early version of a Nintendo Power magazine, Nintendo was showing a photo of Treasure Trove Cove but referenced to it as Hammerhead Beach. This was why at the time people were thinking this was a level, that it was the only beta one that was not reproduced into another game unlike the other ones. The name was changed to match the other names in Banjo-Kazooie which used some form of Alliteration. With Gameshark Code 8036AC41 0020 8036AE39 0007 the player can get this beta beach.
