Hi, welcome. This is for all the achievement hunters, and for fun. I'll be listing the evolutions, the cost for each evolution in case you're like me and never remember exactly how much you need, and other minor notes along the way.

Some minor tips that aren't all that useful but might save you some time:

• Burning Body and the Symbol of Awe ability aren't as useful for killing plankton as you might think. They'll do minuscule damage- it's quicker to just boost your attack and kill plankton.
  
• No, you can't afk with either of the above and a Lure Light. What you can use a Lure Light for is going afk or sitting at crystal for a while. All the plankton will bunch up around you and be easier to kill, but you'll have to manually do it.
  
• if you need to farm for EP, wait until you unlock the Volcano. The enemy there is easy to avoid (dodge 3 times away from it), doesn't attack too often, and the plankton give good EP while being bunched up.

Below are the evolutions in the order they appear in-game.

Bolded parts are mandatory for the evolution.
Italicized parts are recommended based on the cheapest price and number of parts needed to unlock the evolution.
*Means there's a prerequisite evolution to obtain a specific part. Bolded prerequisites are required. Italicized prerequisites are recommended.
Total: This is the cheapest possible price of the parts.

Here's a suggested order of unlocking things for people who don't want to waste time in a fun and charming game. It's organized by the cheapest possible price, unlock difficulty, and whether or not it's necessary to unlock later evolutions.

This list does not include every prerequisite and unlock requirement, only the ones absolutely mandatory that cannot by bypassed via other parts. You also aren't required to unlock things in this order.
