For this project, I created a scenery of life under ocean. The four elements in my drawing are a starfish, which makes a sound every 25 frames; a fish, which spits bubbles and make the bubble spitting sound every 15 frames; an octopus, which swimming in up-left direction and makes tentacle sound every 10 frames when it shrinks before the push to swim forward; and the beach on the soft moving ocean floor accompanied by the mysterious sound starting from the beginning of this animation. During the process, I struggled with matching the sound effects with the animation changes, but I made it working eventually.
