Mooshika Vahana, also known as Musaka Vahana, is one of the thirty-two forms of Lord Ganesha. In this incarnation, the Lord has the divine mouse Krauncha as His mount or vahana. Mooshika Vahana is the one who always holds a modaka or sweet ball in one of his hands and has ears like a hand-held fan. The Lord is short in stature and is the son of Lord Shiva and Parvati. It is believed that the vahana of Ganesha is associated with Karni Mata, a female sage. Hence thousands of mice are found moving freely in the Karnimata Temple at Deshnok, Bikaner.
The Mooshika Vahana form of Lord Ganesha is worshipped with a particular devotional hymn known as Mooshika Vahana Stotram. It is mentioned as follows-
