Deku Butler's Son

The is a character who appears (postmortem) in Majora's Mask. His soul resides within the Deku Mask, while his body became a twisted tree within the passage between Hyrule and Termina. His original body is replicated whenever Link plays the Elegy of Emptiness while wearing the Deku Mask.

After leading Link to the Mask of Scents, the Deku Butler apologizes to Link for traveling so fast, stating that Link reminds him of his son, whom he used to race with through the labyrinth. Later, after Majora is defeated, a scene is shown where the Deku Butler goes to mourn at his son's remains.

After reaching the Clock Tower for the first time, it is not possible to return to see the Deku Butler's Son ever again, due the closing of the interdimensional seal between Hyrule and Termina.
