Items

Found within powerup pods, balloons, huts, and some enemies are items that Otto can pick up. These include weapons, tools, or atoms. The inventory of weapons and some items are shown in the weapon selector. A maximum inventory of 99 is allowed for any item. Every inventory unit will account for 150 points at each end-level bonus.

Powerup Pods can only be opened by punching or by touching while enlarged from a potion. The pods themselves may sometimes be contained by a hut, which must be broken open first.

Some weapons or items are regenerated because of their rarity or great dependence.

Atoms
Atoms are naturally existing throughout the terrain, and also will be released from defeated enemies. They are they only items in the game that can simply be walked into to be aqquired without needing to be picked up. They will fill up the meters according to their color when being gathered.
