The little green dinosaur is back in BUST-A-MOVE 4. Take control of him as he tries to eliminate the colored bubbles that are crowding his airspace. With a bubble-shooting machine, the dinosaur tries to connect three bubbles of a single color to eliminate them, as well as any other bubbles they may be touching. This time around, falling bubbles will seek out other bubbles of the same color to make chain reactions. The simple and addictive gameplay of the BUST-A-MOVE games has returned with a vengeance.
