Bubble Bobble is an arcade game by Taito. The game features twin Bubble Dragons, Bub who is green with yellow spikes/horns and Bob who is blue with cyan spikes/horns. Together, they journey through the Cave of Monsters to rescue their girlfriends. They move over a system of platforms, busting and pushing bubbles, avoiding enemies and collecting power-ups. Bubble Bobble is my all time favourite computer game and Bob and Bub are the cutest computer game characters ever.
