Mogma

Mogmas are a highly civilized mole tribe featured in SS undefined. They live on Eldin Volcano and have the ability to dig into and out of the ground. They are friendly toward Link and claim to always honor their debts, but are also somewhat greedy and enjoy Rupees and other treasures.

History
When Link arrives at Eldin Volcano, he learns that Bokoblins are invading Mogma villages, and he must get rid of them in order to enter the temple. After Link defeats a colony of Bokoblins for Tyto, he gives the young hero the Digging Mitts in gratitude. When Link arrives at the Earth Temple, he overhears Ledd and Cobal talking about a key that will open the gate to the temple, but the key had been broken into five pieces and hidden by Bokoblins. As Link requires the key to enter the temple, he must use Fi's dowsing abilities to find the pieces and dig them up.

Trivia

 * "Mogma" may be a portmanteau of the Japanese word for mole,, and "magma". Additionally, Mogmas also have additional facial features resembling dogs, and their name can also be a portmanteau of "dog" and "magma".
 * Most Mogmas are named after metals or minerals, with the exception of Tubert.
 * Mogmas tend to mistake Link for a Bokoblin upon first inspection; this may be based off of the fact that moles, in real life, have generally terrible eyesight.
 * In the French Canadian version of the game, Nackle's and Tyto's names ("Nick" and "Titam") are interchanged.
