Instructions
Accomplish all the missions and tasks. After some tasks, you'll be rewarded with an Energy Spark. No other ways exist to get these particular Sparks, so complete all tasks you come across.
Keep an eye out for items of value, such as Hook's Cutlass, which can be traded at the museum for Energy Sparks. This is particularly useful if you have trouble locating the hidden Sparks and need one to power up a projector.
Pay attention to potential hiding spots as you play, usually in places that are obvious, but that you don't pay much attention to when focused elsewhere. You can find some Energy Sparks hidden in these places and retrieve them by simply stumbling across them. For example, in Ventureland, an Energy Spark is hidden behind the projector.
