Make sure to feed the pets or they die. Click 'f' to 'hold' the food. Click 'b' to put the food back. When the animals are big enough, they will begin breeding. Click 's' to go to the shop. Select your shopping by clicking once on an animal. The 'BUY' button will acknowledge your purchase by turning orange. Click 't' to return to your 'tank'. Click space to clean the tank. If you buy multiple octopi, it is best to wait a few seconds after each purchase, or else they may swim all together like dancers and you will never know how many you actually have in the tank. You can also click on the big light up the top.
All pets and the plants based on Scratch sprites. (I'm quite lazy when it comes to costumes.) WARNING!!!!!!! Do not buy too many animals...... or else this may not work very well. If you start seeing clumps of bubbles appearing, click the stop button immediately.
