Dr. Left

Dr. Left is a biologist in Horon Village. He studies Cuccos and give Link the Cuccodex, the first item in the Oracle of Seasons trading sequence, in return for lighting his torch.

Quote from The Legend of Zelda: The Minish Cap Dr. Left figurine: "A gruff-talking academic type who is obsessed with studying the Picori. He doesn't seem to be aware that there is a Minish living in his own house."

On a side note, it can be presumed that this character is in some way related to Sim City's Dr. Wright, not only due to the obvious link in last name, but also an uncanny likeness in hairstyle and colour.
