Shells are the main income (and expense) of the player's very own Virtual Aquarium and have currency symbols of a small, yellow scallop (Storeshell.png).

Obtaining shells

Shells can be collected in five ways:

  1. Bonus Round - After completing five levels in Adventure Mode, a bonus round will ensue wherein players have to collect as many shells as they can before time runs out. Collecting the same type of shell several times in a row up to a maximum of 10 grants 80% shells more than the base value. After completing Adventure Mode for the first time, Bonus Adventure is unlocked. In Bonus Adventure, shorter Bonus Rounds will happen after every level.
  2. Time Trial Mode - Converts 5% the money earned in the level into shells once the time limit has been run down.
  3. Challenge Mode - 2,000 shells for Tank 1, 5,000 for Tank 2, 10,000 for Tank 3, and 20,000 for Tank 4
  4. Fish and Pets - Creatures that are housed in the Virtual Tank will periodically drop shells when properly fed. Shells collected by Stinky and Clyde in screensaver mode will count towards the player's shell total.
  5. Codes - Players who have completed the first five levels of Adventure mode can type "give" into the main menu to open a prompt that allows players to transfer their own shells into other accounts on the same system
