If you have made the 100th stage, you get about 1.000.000 points.On the 100th stage you first have to get the pots with the flashes and then throw the flashes from the bubbles towards the enemies.If still no life has been lost until level 50, a white door will appear which teleports you to level 70(!).If you touch it, you get into a bonus level filled with diamonds, where you can collect 432.000 points and then get to level 22, 32, 42, 82 and 92. If no life has been lost until level 20, 30, 40, 80 and 90 instead of the extras a door appears.This is more difficult in singeplayer mode. Some levels require to jump higher than normal.In multiplayer mode, one player has to spit bubbles while the other player jumps on them (jump on the bubble and then direclty on the higher spot or else the bubble will burst).Three great flashes are fired which you should collect. Flashing cross: The monsters get destroyed. Per jewel collected you get 10.000 points.
Yellow cross: Bub or Bob shoot fire balls with big impact.
Joystick upwards+right: jump to the right.Joystick left/right: move left or right.
You should not take too much time to clean the level. After a certain playing time, if not all monsters are caught, the chief monster "Baron of Blubba" appears. They may cause a saurus to walk much faster or to make bubbles faster, the whole cave to turn into bonus items, the saurus are placed into another cave or they are just bonus points. Every now and then also other items appear, extra symbols which cause strange effects when collected. It then turns into a bonus item, which you should collect as fast as possible to get points. If they can enclose a monster in such a bubble and let the bubble burst, the monster is knocked out. Fortunately, the brontosaurus have the peculiar ability to make stunningly big bubbles unter water. When touching a monster the two lose one of their lives. In each of the 100 caves different monsters are about. The two now need to go through exactly 100 of such caves until they have wrestled their brontosaurus females from the hands of the evil Baron of Blubba. Indeed a meanie has kidnapped their two girlfriends and hides them in an underwater cave. Bub and Bob, the two small brontosaurus from next door are really angry.
