Fantasy Zone/Shop

Throughout the game, you will have an opportunity to use the money that you scoop up from defeated enemies to purchase upgrades for Opa-Opa. In order to buy items, you must locate the Shop balloon. When you see one, collide with it to enter the shop. The Shop balloon will not remain in the stage forever. If you do not visit it, it will return to the sky after a period of time, only to return later on. You keep all items that you purchase from the shop until you lose a life.

You can buy as many engines, weapons, and bombs as you can afford to. However, only one of each item can be active at any time. Engines do not wear off, but weapons and bombs do. When they do, you automatically revert to your original default weapons. In order to activate any weapons or bombs that you have in reserve, you must find and collide with the yellow Select balloon. When you do, the weapon selection screen will appear to briefly allow you to configure Opa-Opa.

Engines
Each of these engines increase the speed of Opa-Opa. The increase in speed correlates to the price of the engine. The price of the engines do not increase, regardless of past purchases.

Shot Weapons
When you purchase a shot weapon and activate it, you will be able to use it for approximately 20 seconds. After those 20 seconds are up, you will lose the weapon and revert to the default Twin Shot. Each time you purchase a weapon, its price will increase by the amount shown in parentheses.

Bombs
Except for the Twin Bombs, when you purchase bombs, you are buying them one bomb at a time. You can hold up to ten of any type of bomb. After selecting a particular bomb, you will revert to the regular bomb until you visit a shop or hit the Select balloon.
