Dr. Left

Dr. Left is an eclectic, sedentary biologist whom is seen researching Cuccos in, and the Picori in The Minish Cap. Although his character is significant to the plot in both games, he plays relatively minor roles.

Oracle of Seasons
Dr. Left first appears as a Cucco-studying biologist living in a southeastern residence of Horon Village in. In return for lighting his torch with Ember Seeds, he rewards Link with a Cuccodex, the first item in the trading sequence. Whenever Link speaks with him afterwards, the doctor will feed him seemingly random facts about characters or monsters found throughout Holodrum. All his tidbits of knowledge begin with the characteristic phrase, "My books tell me..."

The Minish Cap
Dr. Left later appears in The Minish Cap. Instead of researching Cuccos, he instead seems more interested in learning about the mysterious Picori race (better known as the "Minish"). He is the owner of the overdue Library Book, "Legend of the Picori", which Link must locate within Dr. Left's home and return to the library. Before Link has to find the overdue library book, Dr. Left will not allow him into his house, as he is absorbed in his incessant study of the Minish race. Ironically, Dr. Left is oblivious to the Minish living within his own home. On occasion, Dr. Left will part with some seemingly valuable and exclusive information on the Minish, gleaned from hours of study. This knowledge is laughingly inferior to what is already known by Link, due to his regular encounters with the Minish race on his adventures.

Trivia

 * The name "Dr. Left" is a pun on a nearly-identical character who appeared in a previous game, Mr. Write. Of course, the pun on the words write being pronounced as right, and right and left being opposites.
 * In, Dr. Troy plays a similar role to that of Dr. Left; he will offer Link information about various characters and monsters throughout Labrynna. Dr. Troy speaks of the very same monsters as Dr. Left, with the exception of Golden Monsters, which do not appear in.
 * Unlike almost all other humans in, he refers to the Minish as "Minish" rather than "Picori". This is likely to demonstrate his knowledge of them compared to other humans.
 * The game Super Smash Bros. Brawl states that Dr. Left is a mock-up of Sim City's Dr. Wright, not only due to the obvious link in last name, but also an uncanny likeness in hairstyle and color.
