The Secret Sentinel

The Secret Sentinel is both the very last level of Croc! Legend of the Gobbos and Baron Dante in a sort of crystal form. He appears on Crystal Island and hovers above a bottomless pit. He shoots lightning at Croc and can only be destroyed by the simultaneous reverberation of four Beany Bird gongs.

Trivia

 * When Croc defeats The Secret Sentinel, the Sentinel shatters in to hundreds of crystals. Croc picks up one crystal and carries it away, which may explain why Baron Dante has a missing eye in Croc 2 but in Croc! Legend of the Gobbos he does not.
