I just used regular pla plus, light is set to medium brightness in the picture. It will actually get pretty bright if you turn it up.

Make sure to have a good set of pliers and snippers or two sets of pliers for removing supports, you will need to break them apart to pull them out. Leave the supports inside the tentacles , you do not see them.

Light sits inside base (printed on separate plate) and twist locks into bottom of octopus and is recessed so its hidden.

Light is bambu MH001 style
