History
Prior to the events of Sonic Lost World, the renowned scientist, Dr. Eggman somehow got a hold of the Zeti Shell. He travels towards the Lost Hex in hopes of harnessing the power of a group of Zeti named the Deadly Six and using their help to conquer the world. However, it didn't result in what the doctor could have hoped, making him disappointed with the Deadly Six as they are not following his orders even after Eggman lends the Deadly Six have some of his best Badniks. He pulls the Zeti Shell out and starts to blow into it like a horn. The Deadly Six were getting annoyed with the sound the shell makes. However the heroic duo, Sonic the Hedgehog and his best friend Miles "Tails" Prower arrived on the scene with the hedgehog suspicious of the shell as possible trouble. He rushes over to Eggman, despite not listening to Tails and knocks the shell out of the doctor's hands.
