Balloons In Arcade Mode
When playing in arcade mode, there is an easy way to get 40 balloons. Start off with the side that has most balloons. After you lay down a bomb, stand next to it. After it explodes, start pressing A and move around. Since you are invisible, you will be a walking bomb and will get 40 balloons easily.
Once you reach Gamma town, go south and kill the two Orkmen. Enter the coliseum and win
five matches in a row. You will receive 150 gold and the Fusible Transistor.
Free Large Medicine
Equip Kai-man and go under the water. Find a green switch and activate it, then talk to the school of fish. You will get the Fishhook and a Karabom will join you. Take the Fishhook to the fisherman to get the Medicine.
