The Emerald Peninsula[1] is a location that appears in the Sonic Underground television series. It is a peninsula located in the seas of Mobius.


The Emerald Peninsula is an isolated peninsula located west of Robotropolis. It is home to several mythical creatures and magical artifacts.[1]


Upon learning of the peninsula's existence, Dr. Robotnik had Sleet and Dingo go there in order to capture people for the Roboticizer. Meanwhile, the Sonic Underground arrived at the island after learning of the peninsula through Cyrus. While on the island fighting Dr. Robotnik's forces, the Sonic Underground ran into Maeve, who allowed them to stay in her house. Afterwards, Sonia found a magical pendant which allowed her to see the whereabouts of others from a distance. However, it started to make her body disappear, and in order to prevent this, Sonic and Manic tracked down the pendant's second half and saved her. Maeve, revealing her fairy-like form, then used the power of the completed pendant to rid the island of Sleet and Dingo.[1]
