Mooth existed as a merchant and made his home on Endor's forested satellite, as referenced here.
His business frequently involved interactions with the Ewoks residing in Bright Tree Village during their yearly trading event. Mooth possessed exceptional sales abilities, notably demonstrated when he convinced Wicket Wystri Warrick to exchange his Monmon seeds for a rock pendant, without realizing that it was actually the lost tooth belonging to the Rock Wizard.
The voice of Mooth was provided by John Stocker during the inaugural season of the Ewoks animated series.
