Made for Scratch Camp 2021: Week 2. I have added large transparent circles to the shark and jellyfish, and used the whirl and fisheye effect to produce the stretchy motion. This project owes a lot to the following innovative projects: 3D paper effect with fisheye by @l3ccm: https://scratch.mit.edu/projects/534529231 Jumping Sprites Effect! by @yqo: https://scratch.mit.edu/projects/534841197 ... and to a certain extent my own project Inverted Whirl Effect (Static Center): https://scratch.mit.edu/projects/545077641
