This mode is acchieved by splitting the top half of B'boom. The section which forms the mandrill's chest, splits and folds out to review double-barreled cannons on each side of him. Then there is the main gun. It is actually B'boom's gun, the same one which comes out from the mandrill's mouth. Under the gun section, there is a third head. Look's like the alien from Aliens. This platform is supported by the legs of the mandrill. On the back there is a space big enough to hold a regular beast (Rattrap could sit), so it becomes a REAL battle platform.
This guy's feet and hands is the mandrill's feet and hands. The monkey head is on the chest and on both sides of it are missile pods which don't shoot missiles. It's the same part which forms the cannons in the platform mode. His gun as I've mentioned above is the main gun of the platform mode. Two missiles are provided which this gun can fire. Waist swivels, upper leg swivels, allowing great poseability. I have to mention this. The ball joint which connects the arm to the body looks pretty fragile, so be careful not to break it. There are two flaps which come from the monkey's chest which hang out and cover the robot shoulders, well, they look outta place. Oh yeah the head... Well the head. Hmm..I think he acctually has hair! It's kinda in flattop style. And boy does this guy look angry!
From what I heard my friends say, B'Boom is better than Transquito. Well, he sure sells better than Transquito!
