The Bongo Tiger is a type of Ninjago wildlife native to the Forest of Tranquility.
Despite its fierce appearance, it can be soothed with music, which its species loves to hear and play. It is unknown if they have any preferences (although their name suggests that they enjoy bongos), but their general love of music makes them fairly peaceful - if nothing else, nervous travelers can avoid them by steering clear of areas where they can hear music, as Bongo Tigers will likely gather there.
