On second thought, its old entires say "as 9' tall elephant"...elephants are Huge. I know it's late in the game, but I think it could easily be Huge.
Support for this case:
From MM Elephant entry: "This entry describes an African elephant. Indian elephants are slightly smaller and weaker (Strength 28), but more readily trained (Wisdom 15). These statistics can also represent prehistoric creatures such as mammoths and mastodons."
From Wikipedia: "The Asian Elephant, sometimes known as the Indian Elephant (Elephas maximus) is one of the two or three living species of elephant. It is smaller than its African relatives, and the easiest way to distinguish the two is the smaller ears of the Asian Elephant. Asian elephants tend to grow to around two to four meters
(7-12 feet) in height and 3,000-5,000 kilograms (6,500-11,000 pounds) in weight."
So, if a 7-12 foot tall indian elephant is Huge in D&D terms, methinks the baku should be as well.
