There’s also the challenge from BlobSponge:
Given that the hint they gave for Electric Trilogy is that you need to electrocute three targets and the image shows Haven Island, chances are it’s this challenge under a different name.
The Adding Fuel to the Fire one is tougher, but given its title and the fact that three different people had a challenge idea for unlocking the Oil Canister that were very similar (myself included), it’s probably the Oil Canister.
