Bananawani

Bananawani (バナナワニ) (called Bananagators in the English versions) are giant crocodiles with a banana-shaped growths on their heads. They are so fierce that they even prey on Sea Kings and are to date the Sea Kings only known natural predator. Despite their strength they were easily defeated by Sanji. They are classified as type "C" creatures being "Big Savage". Crocodile had many Bananawani as pets in his old (now destroyed) casino in Rainbase. He could control them as they were often seen in the room with him and Robin without any sort of aggressive attitude toward either of them. Crocodile seems to have had them well-trained as they would also follow Crocodile's commands such as eating Mr. 3 and the key he dropped into their den merely by looking at one.

Bananawani is a portmanteau of the Japanese word "wani" (which means alligator or crocodile) and the English word "banana."
