Then merged 2 visible layers together the background and the octopus.
Duplicated layers then used puppet tool to warp the octopus arms and head.
Duplicated 2nd layer and put it first in sequence
Created animation timeline, added layers as frames, each frame was set to 0.2 sec.
Saved and exposed as web GIF.
I found this exercise wasn’t necessarily too hard when following step by step just time consuming. But I am very glad I have learnt this skill and will definitely use it in the future again.
